I bought Power Mirrors / Up/down/left/right and the mirror had a 3 wire. connector attached to it. Sold by LMC Trucks. Now, I have the 6 X 9 manual mirrors that needed replacement but there isn.t any switch nor wiring harness in either door. Is there any way to make these mirrors operational? Any leads on where to obtain switches or wiring harnesses for the model year of 1988 for the door?

 

take it easy there. no need to flood the forums with posts about looking for diagrams for power mirrors. i posted the the diagrams for you 2 days ago over on one of the other forums you posted on. i will post the same response here
this should probably help you out
