Can someone give me a run-down of electrical? My SE does not have a sunroof so I'm looking for power in the passenger-side A-pillar, correct?

Any other electrical knowledge regarding this install you want to throw my way would be appreciated. It will be here in a couple of days so I have no idea how many wires are coming out of this thing to hook it up.

Thank you.

This may or may not help, but it worked for me.

I took power from my fog light switch, but mines a '94.

Assuming mine is a 7-pin mirror, does this look to be correct? Seems to jive from the bits and pieces I've found on our forums. Found this from another site.

PIN 1 = PINK = POWER = +12 volts*
PIN 2 = BLACK = CHASSIS, GROUND*
PIN 3 = LIGHT GREEN = BACKUP LIGHTS*
If not using the backup feature, connect this to ground otherwise auto dim will not function properly.
PIN 4 = GRAY = TO AUTO DIM OUTSIDE MIRROR
PIN 5 = PINK = TO AUTO DIM OUTSIDE MIRROR
PIN 6 = DARK GREEN/WHITE = TEMP SENSOR**

PIN 7 = BLACK/WHITE = TEMP SENSOR**16 pin: (*required; **required if you have a temp display)

Thanks.

The colors may be different, but from what I've read, the pin positions are the same on all GM mirrors.

If you want to use the TEMP part of the mirror, you'll need this TEMP sensor:

Temp Sensor= 15047946
Sensor plug(with 2 wires about 12" long attached)= 12101856

You can make your own plug if you want. I tried the temp sensor that came with my 95 and a few others and they didn't work. The minute I hooked up this sensor the TEMP worked fine. Maybe other years are different.

Temp sensor is coming with. Here'* the exact unit that'* being shipped to me. Where on the mirror do the two temp. sensor wires plug into? Can't really tell in the picture. Looks like it may be missing the temp. sensor plug that hooks up to the actual mirror body, eh?

Pins 6 and 7 (farthest away from the mounting stalk) connect to the TEMP sensor. It doesn't matter which wire connects to which pin. There is no power (12v) to the sensor it just measures resistance.

Pin 1 (closest to mounting stalk) gets a "switched" 12v and if you don't use the "reverse light" connection just connect pins 2 and 3 to ground. Connecting pin 3 to the "reverse" will cause the mirror to "Not dim".

I hooked mine up to measure the in car temp and I still have the ECC one that measures the outside temp.

Sounds good. I figured the temp. sensor had to get power but the resistance thing makes sense. Similar to a fuel guage sending unit.

So it looks like it will come with everything I need?

Well, I bench tested the mirror tonight before I started installing and I'm getting nothing. I've got a good 12v connection (pin 1) and good ground (verified with test light) and I'm getting no read-out. Should be getting something, correct? Did I get a bad one?

Thanks.
