I have a coupe. 01. Im trying to put heated mirrors in a car that did not. The wiring diags i found said one of the black is a ground and the other goes to slot number....3 or 5 in the master switch. I could probably wire that up. The biggie is the passenger mirror. Again, one blk wire is a ground but the other has to go under the dash through 2 relays. IDK how im gonna find them either. I dont want to, I really dont, but i may have to just wire them to the defogger.
Even if i had the door harnesses from cdm accord, theres still the matter of the underdash relays. If anything, i could use the plug that the mirror pigtail plugs into. As it fits the pigtail for the heated mirrors, which i now have, lol.
I could wire it all up but...ugh. Huge undertaking. :\
