hey guys this is my first post here. i just pulled the rear veiw mirror out of a 2003 seville sts today. main reason i want it is to use the compass, but any direction or info on how i could get all the features working would be great. from the reading ive done so far, im lead to beleive that the box that i have attached to it is the compass. it has a white, yellow, black, orange and green wire going into it, then back into the mirror. it had another box somewhat attached to it, and i typed the number that was on it, into google and found out it was some sort of wiper sensor, which i have no interest in using so i took it off. and im pretty sure the little circle peice is for the onstar system becuase of the fact it says to wire to speakers on it.
basically what i want to know is if im correct about what ive said so far, and how i would go about wiring the compass up so it works. im also curious about the tempature sensor and it its built into the mirror, or if i have to go back to the same car and get the sensor out of it. any help, advice or pictures on the subject would be great!
all the wires that clip into the back of the mirror
this is what i think is the compass. all the wires go from the back of the mirror to this
alright thanks for the help so far! so the compass is already in the mirror ready to go, which set of wires would be the power & ground? also, if the compass components are in the mirror, what is the black box that i though was the compass?
another thing, when i look at the digital part of the mirror in the right light, it looks to me like it says F and C with the degrees symbol beside it.

The mirror has display capabilities that GM/Cadillac did not use. For example, the compass can be displayed as a conventional 3 digit "heading" figure instead of the GM default of one of 8 heading approximations (N, NE, E, etc).
If you can identify the manufacturer of the mirror, they might be willing to share internal specifications and external wiring requirements. But don't count on it!
with a little more research i found ground and the 12v source. i hooked them up to a battery and the compass works! the mirror dimmer would also work so im assuming that it is one of the options that is in the mirror itself too?

Re: compass mirror.
If the squarish black box was separate but next to the mirror - and attached to the windshield by clear adhesive - it's the RainSense windshield wiper sensor module. Maybe all the wiring bundles into/through the mirror umbilical.
JimD, Is there a magic button push sequence that will display heading in digits vs. the useless cardinal compass points ?
Here are the schematics, location view, calibration procedure, and connector pin out for the 2003 Seville inside rear view mirror. These are from the 2003 Cadillac Seville Factory Service Manual (FSM):
