Window motor question
Folks, changed doors on 71 to 77 doors, noticed window motors are the larger(good move GM), on the 77, one wire is down another is up, stupid me sold old doors before checking if they operate the same,
is there any difference in wire harness (except for plug in to motor), can I use same old harness? (on 77 doors)

If it's still a two winding motor (case is grounded, power to one wire goes up power to the other wire goes down) it should be the same. Newer cars had single winding motors where the two leads have power and ground hooked to them one way for up and reversed both to go down, Not sure if the c3 ever got those or not
