This isn't about my direct conversion but should as a base for it. I do want to share what I have so those who want to can have some reference info to help guide them. Now to start off for those who want to try to be stock looking it'll be a challange for most. The '86-'88 Monte Carlo & '86-'87 El Camino owners will have it easier as the share the samestyle mirrors as the C4 Vette, 3rd gen F bodies, Fiero & '86-'90 Caprice Classic. All others are limited to '81-'82 Vettes for sport mirrors & 80's B, D, RWD C bodies & most '79-'85 E bodies for chrome mirrors. Note Cadillacs have "Cadillac" casted into the housing. Some of the chrome driver side mirrors may have a outside thermometer on them. There are other mirrors out there but would require custom fitting to be used.
With the control switch on GM's are of three set ups: single switch with a L & R switch, single switch with the knob being able to select L & R, dual switchs with one for each mirror. Some can directly replace the cable control lever like the '91-'96 B bodies & other late '80's/early to mid '90's cars. The '80 B/C/D/E also fit the same but about all of them have dual switch & would be ideal for those that have twin remote mirrors. C3 & '84-'89 C4 Vettes will fit but uses the L & R switch. C3 switchs have a very heavy "Vette Tax" being new repop or used. Most stand alone switches can easily be fitted in the door panel or center console.
Wiring may be something that'll throw things off as not all the colors listed in the diagrams match what is used. The C3 harness I have don't come close to what's in the '81 CSM I have. Even the motor wires most likely won't match. It's best to grab as much of the donors wiring even if you're going to source from different models to get it all to work just to ensure you'll have an idea of what wire does what. Also, just because everything is GM sources doesn't mean the colors will match.
From what I've seen with motors, the C3 & C4 (& others that uses this sport mirror) Vette mirrors use a simular motor with the difference of the wire color, wire entry to the motor body & wire circuit based on how it's mounted to the mirror housing. There are other that use the same style motor like '95-'99 ('00 Lumina) W body (possible with '88 up W body also), '86- about '93 E body, '97-'05 W body Malibu & Cutlass (to '99). I don't want to get too much as this is something I'm learning about as I go but I'll add the wire circuit function in realation to th control switch will be based on the clock position of the motor itself.
Here is some wire diagrams for the what I have. Both that is in the '81 Corvette CSM, '87 Caprice Classic from the '87 B/G electical manual & '97 Monte Carlo/Lumina from the '97 Chevy/Olds CSM Vol 2. The Cutlass Supreeme is very simular so I passed on it for now.
I'll be adding as I go & I welcome anyone else to add to this.
