Can anyone confirm that Canadian Spec NSX Day Time running Light control Unit 38260-SL0-A01 is Mitsuba RZ-0138? I would be grateful. It is located on the back of the Glove Box. In addition to other ABS, Security, cruise control and Door Lock modules

Maybe yes; but, I would not put a lot of money on it at this point. This is the plug configuration for the Mitsuba module.

It has the same 7 cavity and 4 cavity plug configuration as the NSX DRL module (page 23-176 of 1991 service manual). However, the cavities that are populated with terminals in the NSX plugs are fewer than the number of pins in the Mitsu module. So the modules may be plug compatible; but, may not be pin compatible. That could be because the NSX does not use all of the functions in the module which means that the Mitsu module might work. Short of buying and trying, the next step would be to find a wiring diagram for one of the Civics that the Mitsu module was used in and compare the pin assignments / functions to the wiring diagram for the NSX.

Page 7 of the wiring schematics in the 1991 NSX service manual shows the schematic for the DRL module. It doesn't give pin / plug numbers; but, it has wire colors and by referring to page 23-176 you can match wire colors (and function) to the positions in the plug. Do a similar analysis based upon the Civic wiring diagram and you should be able to figure out whether the Civic module will work.

Thank you for the quick reply.
Do you have such a module in your NSX?
It would be great if someone with an NSX Canadian Spec took a picture of the module (markings)
I bought Electical troubleshooting for Acura 97-04. I think that my professional knowledge would allow me to make a new wiring harness. It's easy for Pop-Up Light NSX. I wanted to make the task easier by confirming with the owners of Canadian Spec NSX. I was contacting Southview Acura in Edmonton but couldn't answer. They only knew Part number 38260-SL0-A01

This particular Canadian owns a US market car so no module to check. Plus, if I did have a Canadian market car with the module, the location of the module is moderately difficult to get at so its unlikely you are going to get anybody to volunteer to pull things apart to get the module out of the car for a photo. I think your best bet is to get the schematics for the correct model Civic, figure out the pin functions from the schematic and see if they match up with the NSX schematics.

Hi OldGuy Maybe at the beginning I should say that my car is Acura USDM. I imported it to Europe Poland. We have had a DRL obligation for several years. I know that there are hundreds of options for aftermarket solutions, and I have them today. But my goal is to make my NSX 100% OEM. I think there are people on the forum who understand this ... Pictures of the module's location are attached - I am not asking you to disassemble the car into the first parts. Just unscrew the Glow Box. Literally a few screws. I have followed this forum (Electronic 1st Gen) and thought I was in the right place to ask this question. Post Scriptum: We have a micro NSX community in Poland (15 cars currently), most of them from the US market. Unfortunately no Canadian Spec. Economic reasons. We borrow parts to diagnose faults, such as Ignition Coil. It's great that we have a passion for one Acura / Honda NSX model.

If this NSX is of US Specification, there are no connections from the wiring harness for the Canadian DRL Module.....Save your monies and time looking for this to work, unless you want to hack something with the wiring harness

I went through this when I purchased and imported my NSX from the US.

I admit, Bram, I expected some other help from a Canadian.:confused:

If I wasn't stubborn - I wouldn't be driving the NSX today, just an Italian brand.
It's a simple job, I even bought an ETM (Electical Troubleshooting Manual). Especially since all the necessary cables (coding addresses) are nearby.
It's fun and relaxing for me.
For example, I know how to easily convert an antenna so that it goes halfway. Just like in Japan Spec. Cost $ 0, work only.
Unfortunately, I don't speak English - I use the translator.
In the future, I will ask someone around me who knows English well and will post it on Prime.
I am afraid to do it so that there are no mistakes - I am a responsible person.

I am aware of where the DRL module would be - if my car had one. I am also aware of the interior parts that have to be removed to access that location. If this were a matter of opening the hood, popping off a cover and taking a picture I (and probably others) would be happy to oblige. Taking the glove box out is slightly more risky (I have done it) because you always risk breaking the little plastic mounting tabs - particularly now that temperatures have dropped and the plastic will be hard and brittle. Removal of the interior panels allows you to see where the module is located. Getting your hands in there to unplug and unscrew the module involves a lot more work.

I understand that it would be nice to have an original Honda designed installation. I would have thought that Honda would have designed one wiring harness for all markets and just left some plugs unused; but, as Bram notes they didn't. The US market car does not have any of the connectors for a DRL system. If you install the Honda DRL module in the location next to the ABS you are going to have to run wires from the front compartment into the interior and that is not easy to do in a way that is reliable and looks good. A DRL installation that keeps all the wiring in the front compartment will be much easier to do and if you use Honda style plugs (cycleterminal.com can supply these), non split high temperature wire loom covers and Honda cable retainers you can make the installation look like it cam from Honda.

In this particular case, a less than perfect solution is probably the better solution.

Hi Old Guy,

Your first answer was very to the point. The second answer too.
I can see you want to help me.
It is also possible to: You could contact Southview Acura and inquire about the availability of 38260-SL0-A01.
Unfortunately they don't ship to Europe.
I am happy to pay all the cost if you could buy on my behalf. Of course, I will pay the prepayment


Post Scriptum.I don't have to go going to have to run wires from the front compartment into the interior. And cut the covers of wires. As Bram mentioned, I can do hack it.

Southview is about 800 km from where I live; but, I do have a local Acura dealer I can check with. What is the model year of your car. I will pay a visit to the parts department to see if the part is still available and what the price is. If it is available, I expect that it will probably be on critical back order. I tried to order a part that was on critical back order last summer and the expected delivery was 6 months later.

Amayama does not list the part so it appears that JDM vehicles did not use DRLs. Do none of the European market cars come equipped with DRLs? I thought the Scandinavian countries required DRLs. If so, it might be cheaper to try and get the part from A. S. Motorsport in Netherlands.
