no it will not, it should function as the range button.. I do know the flex PCB for it is different so many of the lights on the DIC will be wrong, when I did the 91 interior in my 89 with the 94-96 buttons and such, I had to use the flex PCB off of a 90 for that to show correctly..

the Gauges might work if he swapped to a 92 CCM and 92 PROM in the ECM, but one would have to verify that the wiring to the ECM is correct/same/similar from 91-92

Would be a cool mod if it could be figured out.

Oh yeah he also would need the 92 LCD (Almost forgot about that)

I have the pinouts for the ECM listed at home and I think the CCM is the same

The 90 is a different beast though due to the Power Key and the Knock stuff in an external module

It does function as the range button. Haven't tested the DIC lights yet, except that they all come on with the start up test.

No, we decided against leather for the hush panels - doesn't mold around irregular surfaces as well as vinyl. I am going to do leather on some of the more exposed parts - arm rests, center console lid, and probably the seats are going to get redone. So far Ive had both hush panels recovered and had them make me a new leather shift boot - came to about $200 for those three items.

So I did a quick road test the other day to check out a few things.

As soon as I turn on the headlights I lose all dash lighting - it fades out to nothing. I'm sure this has something to do with the aftermarket head unit and the factory dimming function. Also the new head unit is too bright at night. It has a wire marked illumination but I'm not sure what to hook it up too. Anyone have a solution for me???

The new steering wheel is not centered, thought it was but no it's off by like 20-30 degrees when driving straight. I don't think I can correct it by rotating the mounting bolt holes over one - think that would be too much.... which leads me to the adapter and shaft splines. The NRG adapter logo ends up at about 11 o'clock with the tires straight. In all the pics I've seen it looks like the logo should end up at 12 o'clock.... but when I mounted the adapter to the shaft it seemed like it only wanted to go on one way.... hmmm

For the light as far as the aftermarket radio I need to see how mine is wired.. I will get out to the car in a day or so

Thanks Jeff that would be very helpful. I know this has been done before as there are lots of C4's running aftermarket stereos but my searching has yielded iffy and often conflicting answers regarding what needs to be done with the wiring.

Here are a couple of pics of the steering wheel issue. The stock wheel has larger spline slots at 12 and 6 o'clock so it can't really be installed wrong, not sure about the NRG adapter I used... would have to take it off again to look. It seemed like it would only seat on the splines the way I have it indexed.

I tapped into the HVAC control above Bob they dim in day vs. night from the factory. It seemed the logical choice and it solved the problem. GC
