I am attempting to add a power rear window to my "old ladies" 87 blazer. I have the regulator, rear switch, wiring harness, cable (on the way), and new motor. the new motor did not come with the mounting bracket. my question is where exactly dose the motor mount? I am asuming on the pasanger side of the tailgate but to what I am not exactly sure. one other question is in all of the wiring diagrams I have found blue=window down tan/white=window up orange/black=hot there is also a black wire in my harness. I am asuming this is a ground but it is not in any diagram I can find.
