Ok, discovered on the web where someone added a 91-94 5psd manual with EPS. Based off the write-up and pictures below, it seems as it can be done. What I don't understand is where the dummy plug came from on the manual transmission

Power steering installation
With NSX after 130 types, even by the MT car power steering installing was possible with option, but
With early type there was setting in only the AT car.
If it is not, without being, it can run that much pain without it is, but
While finishing to set after all, and the garage inserting especially descending garage inserting full steering and
Wearing the S when tire, as for something
Keenly it becomes desired power steering.
As for the car 輌 which this time is installed it meaning that the owner is the woman, desiring especially power steering
Because one time it tried challenging, applies
We had decided to work.
Because with Type-S of the fortunate power steering attachment from the part taking car 輌 the part it can purchase with Assy,
In coupe MT car of 1991 type
The power steering for MT there is no additional purchase part and installation was possible.
The power steering unit Assy for MT which it procures
As for the harness because it is cut off, extension was necessary.
You remove the case where is cut off as long as possible the one which future ease.
デファレンシャルスピードセンサ which is installed in the mission.
Ring gear peripheral speed of the diff. is measured with this sensor.
Pulse unit.
It goes between デファレンシャルスピードセンサ and control unit.
The universal joint which conveys revolution of the steering wheel to the rack.
As for this thickness of the spline is different in the manual and power steering because,
One for power steering is used
As for rack itself with one for manual OK.
As for joint installation position
It being such as between the clutch & the brake pedal, it is visible that you remove the cover.
Before removing the rack, this is removed.
The rack of the manual steering wheel is removed.
On manual steering wheel rack
Under electromotive power steering rack.
However it is large, being to be the aluminum make, about the eye which you saw it is not heavy.
The power steering rack is installed.
Everything it can unite the part other than the rack that way.
Without either interference ones complete volt/bolt on.
Pulling out the dummy plug which is installed in the mission
デファレンシャルスピードセンサー is installed.
As for the mounting hole this sensor with 5MT and being processed with 6MT
メクラ is done with the plug.
Pulse unit is installed.
Removing 2 vehicle speed signals from main CP and pulse unit
With the cable it wires in power steering control unit.
Job inside bonnet
First, blower unit is removed
The blower unit which you remove
The wind is sent to the heater and the air conditioner with the sirocco fan.
Among these it meaning that the bat enormous dust has been plugged
Being to be the good opportunity, when it cleans with the air gun, it is good.
When blower unit is removed, it meaning that the interior is visible
Operating efficiency is good.
It removes the carpet of the suicide seat foot the る
Being to be a foot bus speaker, you remove this.
Power steering control unit is installed under the speaker.
When blower unit is removed, it meaning that the hand enters from there
Operating efficiency satisfactory. Rack side and control unit wiring
You connect also the vehicle speed signal.
If there is a diagram, especially difficult job.
In general at above job end
The toe the front to be large being to be the expectation which has deviated
Doing the alignment adjustment after this, operating verifying, it ends.
Trying, installing
When it tries doing actually installation
If already there is no this, the extent which becomes unable to withstand being convenient, it becomes comfortable.
As for the electromotive power steering of NSX
Assist power being small relatively, like the car being not to become unnatural light
You cannot feel strange feeling completely.
Also change of the assist quantity with vehicle speed being well thought
When it becomes speed of sport travelling level, assist is almost gone.
In addition, decreasing also the kick back in the road surface which becomes rough
Very the car becomes easy to handle.
Dramatically is not the extent which bodily sensation it is possible, it is, but
Ratio of the steering wheel power steering has become quick, so is.
Being certainly to be weight ones it does, power steering unit, but
Installation balance station is low and
When it becomes weight difference of normal unit
It is not the case that the car it increases fatally weight because,
If it is not competition only, there is no demerit completely, the て
Being to become very comfortable
I will acquire power steering to your own NSX with the latest job! With it decided in heart.
As for problematical point
Power steering unit when you buy with the new item, is very expensive.
When it arranges with the brand-new part, being to exceed 500000 Yen lightly
To unite cheaply, it means to use the used part, but
Because as for the harnesses it becomes the other electric wire as one unit,
It is difficult to remove just the power steering-related harness from the car 輌 cleanly.
In addition, as for the type which is adopted for the early model AT car
Because control unit the signal it exchanges vis-a-vis AT control unit,
That way, in the MT car without problem being installed
Whether it can do proper control, it is unclear at present stage.
Because from NSX after 1 1 0 types the MT car there is setting of power steering with option,
The rack & control unit with AT and MT have become common.
By the fact that pulse unit is used in place of AT control unit
The vehicle speed signal can be inserted because,
The power steering for AT transplantation is possible in the MT car without problem.
Combination of early type power steering rack and latter-term type control unit,
Or combination and the like of early type unit and pulse unit
At present stage being the unclear point to be many
In the future this work sheet is the schedule which it keeps modifying at the stage which understands.
Old type power steering unit installation 030413 supplementary information
Power steering rack for 100 types AT
Because control unit Assy of 120 model MT cars enters into the hand,
It tried uniting to my NSX.
As for power steering control unit of prior-term type
It is divided into the control unit the left and the power unit the right.
At the latter term this becoming as one unit, being to be lightened rather
When they are this prior-term ones, well enough there is a weight.
Big FET and relay having entered in power unit
The motor of the rack is driven, don't you think? it is.
Is size of unit in early type reason, probably the safe margin for the heat generation of FET?
Is pasted even in the controller of the air conditioner the seal of the example which even here. .
The same manufacturer we would like to see, don't you think? is.
As for this the connector which has come out of the rack.
As for new model the rotary sensor being abbreviated, however it became 1
First stage & as for mid-term type are 2 couplers.
Because this time the private harness does not enter into the hand,
Searching the connector which can be used from the dismantling car, it made to use.
Even in diagram of service book
Because wiring color of the power unit side connector has not come out,
Looking at the early model AT car in order to inspect this
Wiring color is inspected.
If the genuine harness enters into the hand, such hardship it does not enter, but it is
100000 Yen or more it does the harness.
And, wiring color of the car 輌 side harness and why wiring color of power unit side differ.
The harnesses which are prepared to work day.
As for installation of rack
Also the prior-term latter term being similar, without especially problem volt/bolt on.
As for control unit
Installing in the designated place around the reverse side of the glove compartment,
You install power unit under the foot bus speaker.
However also the for the sake of it is in the midst of job it is when you compare to latter-term ones, as for wiring it is many.
As for installation and part of speed sensor and pulse unit etc.
Similar to latter-term ones.
As for feeling after the installing? ?
Actually when it rides and tries comparing the prior-term latter term
After all, latter-term ones texture fineness of control are fast, has become good,
And vehicle speed rises the case where how to end the assist
The latter term is finished considerably naturally.
The previous term being about 40 kilometers, understanding that フッ and assist end,
The steering wheel becomes heavy however,
The latter term the assist impression is gone naturally at 60 kilometer neighborhood.
As for power steering of NA1 ･ NSX
There being 3 types constitute
As for 100 - 120 types control unit & power unit with sectional pattern
From 130 types it has become 1 body
And, to 100 - 130 types as for coupler of rack with 2 as for rack commonness.
The rotary sensor being abolished from 140 types of NA2 and NA1
The rack being modified specification, as for the coupler one.
In other words, as for the rack as for 2 kind control units it becomes to be 3 kinds.
As for testing with KSP
It meaning that are just the previous term of 110 models and the latter term for NA2
Hit to mid term unit of 130 models which some kind of feeling
Presently it is unclear.
Some days ago
Because 130 type control units for アキュラ are procured,
When it tries using this in the latter-term thing rack
Temporarily although it does, error coming out directly, it stopped assist.
It is thought that is, because there is no revolution sensor input.
When it combines to 100 type racks where I have united this the notion that how it becomes,
The next time we would like to try checking.
Previous term operation verification in between latter term 040102 supplementary information
In latter-term rack previous term and as for combination of mid-term unit
Being latter term, because the rotary sensor is abolished from the rack it became NG, but
Mid term and how combination of latter-term unit in the prior-term rack?
It tried verifying.
In prior-term rack as for combination of mid-term control unit
Because 130 types NA1 hit to that usually,
In regard to operation it understood beforehand that it is not problem, but
The result which is tried with NSX of the customer after all problem it was not.
By the way
The actual place how does feeling differ at the previous term, mid term and the latter term?
Is, but
To the last, it means that I feel but it becomes like below.
* First, it is the early type power steering which is adopted for NA1 of time before 120 types but
As for this control unit with power unit and 2 divisions,
It united to early model AT car and my NSX, hits to mono that.
* Vis-a-vis this
As for mid-term type power steering control unit
The latter term and appearance being the same, it becomes 1 body,
However with actually steering feeling it is not different from early type largely
It seems that method of ending the assist becomes latter-term similar smooth.
Is not actual travelling and you verify with rear wheel lift rise when,
As for early type however it stops feeling most assists at about 40 - 60 kilometers
Mid term being about 80 - 100 kilometers, the assist impression keeps being gone.
As for rack at prior-term mid term the same mono with,
Those where only control unit is modified are mid term.
* And, with the debut of NA2 it is the latter-term type which is adopted, but
It is built in to the rack
The rotary sensor (has detected steering direction and steering speed) being abolished,
Has detected control force and direction of rotation rotation direction with only the torque sensor.
Control unit very appearance is the same as mid-term type, but
Inside differs attendant upon revolution sensor abolition.
Power assist bodily sensation,
It was seen with mid-term type
In addition to the smoothness of how to end the assist for vehicle speed,
Turning the steering wheel, the case where you inserted control force
The response of assist has improved markedly.
Previous term & mid term
When the steering wheel is turned, the phone (with steering wheel outer circle several millimeters) lately just a little
Power assist starts.
As for this understanding in bodily sensation when finishing to place at the parking zone about, being to be, it does, but
The human you feel, feeling
The latter term you are moved by lightness of the amount natural operation without of having lag, it is.
In other words, at previous term and latter term
Smoothness of how to end the assist for vehicle speed and,
Extremely, the low-speed limits in the point of the response of the assist which can be put
It means to be the merit which two bodily sensation is achieved.
If at the previous term and power steering has been attached at the latter term, as for operation being easy,
If vehicle speed rises, assist is cut off, therefore it is
If you say that it is good with whichever, but so what
When it tries comparing, it finishes to place and in the polar low-speed limits
Don't you think? latter-term power steering assist is smoother.
This
It depends on control unit, mono being,
You wanted to know whether it is for efficiency improvement of rack side
It tried experimenting with my NSX.
First, in my prior-term rack
It tries combining latter-term control unit.
Processing the harness temporarily
As for the rack with while it is the previous term with control unit as a latter term operation check.
Temporarily, there is no error, and the like verifying that it assists normally.
But, as for the responsiveness for control force being similar to the previous term & mid term,
It did not become the smooth assist impression the latter term of seeming.
Just the rear wheel lifting raising, while cutting the steering wheel on left and right, increasing vehicle speed
It tries checking the change of assist power when,
As for change of the assist quantity for vehicle speed you feel same as mid term & the latter term.
Result,
It combines latter-term control unit to the prior-term rack, but possibility
As for being obtained with mid-term feeling,
It understood that as for the early responsiveness which the latter term seems it is not obtained.
As for smooth feeling of latter term
Perhaps the torque sensor of the latter-term rack the excellence therefore.
As for charm of latter-term power steering
It meaning that smooth early responsiveness is larger than how to end the assist
To the thing which is left temporarily as for my power steering as early unit
You reset control unit to those of the previous term.
But as for acquiring power steering to NA1 with the rear attaching possibility
Being most effective in the cost aspect to utilize the medieval times of the prior-term AT car whose procurement characteristic is good
If the new item is bought
It means that it is best to arrange in all latter terms.
In cost aspect
In case of the new item the previous term becomes highest, the mid-term latter term the same, but
Don't you think? victory rises to the latter term in the point of feeling.
At above it is adopted at present stage
You verify related to power steering of NSX & data acquisition the end comparatively.
Lastly
The owner who has interest in regard to the power steering of NSX thinks that large number it is, but
This being dramatically driving easy by the fact that it installs becomes pleasant.
There is no demerit.
Also weight increase barely is
If conversion it does in latter-term type ABS, almost it is equal to nothing with deducting, probably will be.
Cost is required, but recommendation degree is very high, don't you think? is.
