I picked up these 2 from the wrecking yard today.  They are all i could find in the entire yard.  both from 99-02 ish park ave ultras.  They do not have temp unfortunately

The butons are for comp/mirror.  the mirror button just toggles the autodim on/off.  They work.  anyone have any other coments on how to program it or other features, feel free to chime in.

Can anyone tell me what the extra wire harness is coming out of the back and going to a black box with the little circuit board?

I really want to find this same mirror , but with the comp/temp feature.  and preferably with the dual display  screen,  if anyone comes across one

Outside Moisture Sensor (Option CE1)

The outside moisture sensor monitors moisture accumulation on the windshield and commands the windshield wiper module / motor. The windshield wiper / washer switch intermittent positions are used to activate the automatic operating mode and to adjust the level of sensitivity to moisture accumulation. The windshield wiper module / motor sends the status of the windshield wiper / washer switch to the moisture sensor using a PWM voltage signal through the moisture sensor signal1 circuit. Moisture sensor signal2 confirms that the moisture sensor is receiving the moisture sensor signal1. If communication is lost, the wiper module / motor will use the inputs from the windshield wiper / washer switch in the intermittent positions to operate the wiper module / motor at delay intervals.

Must be for the compass, i disconnected it and then the compass lights up blank.

For anyone looking for one of these, they fit the old style 99 and older Tahoe as well. We had one in the shop today with it. I wanted to quietly swap it out for a normal mirror!

Never mind, got it figured out.

If anyone is doing this and has a 16 pin mirror, not a 7 pin, I can tell them how to wire that one now too.

I'll keep watching. This came from an Equinox, I think a 2005. I bought the sensor new (Equinox was hit in the front, couldn't find the sensor) for about 7 bucks. I may have another connector for the sensor if you find a mirror but no sensor or connector. I don't have a spare mirror connector though.

I didn't put it in the truck yet. It was too cold to bring that ice cube into my garage! I bench tested it on the table and it worked fine though, temp was right on. I didn't calibrate the compass yet but I don't care that much about it anyway.

As long as you buy a mirror for the correct application.

I can't seem to get the Onstar to work in my 97...

Or my 66 GP...

I just figured out I have compass and temperature on my I Phone     wow    

I finally found one!  looks just like the pics at the start of this posting.  dual line display.  got it built and installed in my 91 silveado,  works mint, cool option!!!!

I got a second one that is also a gentex, out of a equnox or something like that.  its a little bit different shape, with a small screen for the airbag(who cares), not really even noticable.  but, it has a bigger harness with about 14 or 16 pins.  Anyone know how to wire that one,  i should only need 4 wires still.

I just found this that I had saved. Is this enough?


TOP ROW - Right to Left from REAR of plug
PIN #1,2,3,4,5 = Empty
PIN #6 = Light Green / Black tracer [AMBIENT TEMP SENSOR 12V] goes to TEMP SENSOR, pin#1, Light Green/black tracer wire.
PIN #7 = Gray / Black tracer [AMBIENT TEMP SENSOR GRD] goes to TEMP SENSOR, pin#2, BLK / red tracer wire.
PIN #8 = Black solid [GROUND] goes to GROUND point, {IF}, left kick panel.

BOTTOM ROW - Right to Left from REAR of plug
PIN #9 = Light Green [REVERSE DIM INHIBIT] goes to BACK-UP LIGHT RELAY, Tundra connector B3, pin#1, GRN / red tracer wire.
PIN #10,11,12 = Empty
PIN #13 = Yellow solid [12V SWITCHED POWER] goes to CIGARETTE LIGHTER, Tundra connector C7, pin#2, GRAY solid wire.
PIN #14,15,16 = Empty

TEMPERATURE SENSOR
PIN #1 = Light Green / Black tracer [AMBIENT AIR TEMP SENSOR SIGNAL]
PIN #2 = Black / Red tracer [LOW REFERENCE]

*TIP#1: the wires from the temp probe are not polarized. Meaning, the wires can go in reverse order and it won't make a difference. The Low REFERENCE is the "ground" from the low voltage (~5V) supplied to the probe. The probe doesn't care which wire it gets the juice from or which one it returns the low ref back to the mirror's ecu. Get it? No? Read up on how a temperature probe works and you will.
