    I am replacing the doors on my 78 Blazer with doors from a 90 Suburban and have a wiring question. I have the power windows and door locks working, but I am not sure how the electric mirrors are wired. The left side has three wires (yellow, white, and blue) The right side has five wires (yellow, white, blue, orange and black). I am guessing that the yellow, white, and blue wires from one side are connected to the matching wires on the other side. The black wire is probably ground and the orange power. Can anyone confirm this? What size fuse is used for the power?

    The 90 Suburban doors are basically the same as my 78 Blazer doors (except for some rust and dents). The 90 doors use different window regulators and wiring, but these swapped over from my 78.

    I have 4 .jpg's that make up a complete mirror wiring diagram for a 91 (I'm sure it's the same as a 90), if you want them let me know where the send them (each approx 400kb). /forums/images/graemlins/thumb.gif
