Vehicle Speed Sensor-Easy tap location?

4 December 2001
San Pedro, Ca.
After doing a search with no luck, may I ask of an easy location to tap the Vehicle Speed Sensor, which my new navigation requests I do. Thanks :confused:
I'm not sure if the instrument panel is the same on later cars - something I recall that the pugs were different.
On an early car, it's a yellow/red wire on pin A-21 on the green plug that goes into the lower right corner of the panel

This wire also goes to the ECM, the Cruise Control & the EPS - the EPS may be the ideal location to tap off if you are locating in the glove box area.
That would be pin A-12 on the EPS module, again yellow/red.
If possible you should check with your service manual for your year to be sure nothing has changed.

Here's an extract of the EPS schematic -

Apparently not - What made me think you had a later car? :confused:
Luckily your name isn't Jack!

Is it an auto?
Of course it won't have EPS unless it is (Although I wonder if the harness and plug is still there??? Hmmm - that would be interesting to check .... )

Do you need the diagram for the instrument panel?
:smile: Well, almost everything (considering I don't recall every meeting you in person). My car is a manual (6-speed thanks to Chris a SoS), so no p/s.
I would rather not pull the instrument cluster (done that before thanks to Stacy), so where else might I be able track down that little yellow with the red stripe wire? Where is the other end? Where is the Cruise Control module? Thanks again :wink:
It would be nice to connect ultimately - I "hear" you have a pretty nice sound system, be good to compare.

You don't have to actually pull the panel - just the peripheral parts, knee bolster & the brace behind it to get access to the plug

However, cruise control might even be easier - I didn't actually realize it was in this location behind the glove box.

As I was passing the GPS antenea lead past the ECU I noticed a yellow/red wire staring out at me, but then I started noticing that other things had yellow/red wires too :confused: . So I did as you suggested and grabbed the one behind the glovebox at the cruise-control unit plug. Thanks again for your help. :biggrin:

I'm trying to do something similar on my 92' so I dont have EPS.
Any idea for the speed sensor/pulse wire ??

thanx in advance
I just completed my install and I hooked at the power steering computer it was closer to the stereo. I would guess the wire color changed in 95 to orange from yellow/black. I saw that there were various shades of orange wires all over the place, just make sure you use the correct one.

Ah, you must have done this for the Eclipse unit. I was doing the same install this weekend and that VSS wire made it all the way to the back at the ECM. :)

Yes, tons of choices to tap into...
