I just acquired a set of C-4 electric seats 1995,, I have the harness and connectors, I need a wiring diagram so I can make them functional,, thanks for the help,,, if you put a set in your car,, how difficult was it to bolt them in?
I just got a eye opener, one guy said the seat are too tall and the electric rails have to be removed and the front mounting flange cut down,,, now that was a kick in the lower, any way ,
There are two switches, one in each seat bolster right and leaft side of the seat, One pulg has two pins, the other plug six pins. I guess lombard, window, seat forward and back ,, seat up and down,, possible door lock. Like I said ,, each seat bolster has a switch plate.
Thank you for posting the diagram,, I'll check it out today. It is a little disturbing to find out, I may not be able to install the seats with the electric drive rails. To get the electric rails in, I would have to redesign and lower the existing floor. One guy on DC posted some pic's of his install and it looks really great but no electric drive.
I might have to use my manual rails to lower the seat.
Seems like every time I get into one of these mods, its a major mountain to climb. I think GM used the 77 car as a on the road R&D project car!
