Power mirrors

Does anyone have a wiring diagram for the power mirrors in a 89-91 burban or blazer they could post or email me? I got a set off a 90 burban today and got most of the factory wiring and noticed it daisy chains thru the doorlock switch. I'm curious of why it does this and how to bypass it so I can test them on the bench before I install. Thanks in advance.

I went down in the basement and studied the harness better and it looks like the doorlock wires run thru the same plug as the mirrors. If anyone can confirm this please let me know.

Re: Power mirrors

Nevermind. Two of the three doorlock wires run thru the same plug as the mirror wires and have nothing to do with the mirrors. Hooked up the harness to a drill battery and the both work fine.
