power rear window

[hognutz]

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.

okay I found out where the motor goes. I just need to make or find a used bracket.

I still have not found what the black wire in the harness is for. the motor only has two wires. It thouls be grounded already I would think.

I Thought the same thing made my own harness from switch to motor. Doesn't move. So I have checked voltage through switch got power nothing moving on motor through either I have bad new motor or simple electrical circuits are confusing me. Think I'll open a beer and think about it some more.Good Luck

well got it working. the black wire is a ground but mine works without it for me.

basicall all I needed was power live at the rear switch and and your are good to go.

you can test your motor by just applying 12 directly to it making sure that the motor case is grounded.
