Is this what you need?
The automatic dimming mirror:
There are two light sensors (photocells) in this mirror:
One important safety feature is that the mirror automatically returns to the normal state whenever the vehicle is placed in REVERSE. This feature makes sure the view in the mirror is clear and bright when backing up.
To turn on the automatic mirror, turn the ignition switch to RUN.
The mirror can be temporarily darkened by covering the outside light sensor on the back of the mirror case.
Here is where they hook up. You will need to find connector C244 behind the left kick panel.It may already have the wiring there.
We will try this again.
I don't know how this will turn out.
Here is 2 of them I got to reduce the others to get them on here
Here are the other 2
Can you make these out?
Basically you will not need the auto headlamp part hooked up on pin 2
The slide bar is for the automatic headlights and I don't know how you would get that feature to work on a 2002 model because that is a total different set up.
The 2002 model just used the auto dim feature which just requires a power and a ground to the mirror.It also had a 3rd wire which just hooks to rear body control module and when you go to reverse it blocks the diming feature.
If you hook power to pin 6 and ground to pin 4 of the 98 mirror the auto dim feature should work. If you want the disable feature for reverse to work you will have to hook pin3 of your mirror to pin4 of the C3070b connector at the rear body control module,BK/PK wire.
Do you already have automatic headlights on your vehicle?
Yeah the 2002 the instrument cluster module is what controls the auto headlights and it would have a sensor in the top left corner of the dash. Total different set up. You would have to change alot of stuff like cluster,harness, etc to get this feature to work and probablt the front electonic module also.
I would just wire up the diming feature and not worry about the rest.
The 3rd wire is to disable the dimming feature when you go to reverse,this is all it does.
Yes you would have to run a wire from there to the right rear corner of the vehicle to the body control module. It is behind the quarter trim panel just forward of the tail lights.
