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
inside of "the compass"
pretty sure this is for the onstar
