Wiring Diagram Help? 89-91 Power window/lock & Brake Switch

[NastyBuzzard]

Can anyone help me find some actual wiring diagrams that actually tell me what the wires are or what they do.

I am using 91 Suburban doors on my 87, but I am using the wiring harness from a 2001 Silverado for my LSX.

I am integrating the newer wiring harness with the old switches. I have the headlights, and tail lights working. I even have the key fob working the door lock actuator.

However, I need help wiring the 91 switches to the 01 harness. So I need something telling me what all those wires do coming from the 91 switch, as well as the ones for door locks and the power mirror as well.

Help?

If you could help with wiring diagrams for the 01 as well that would be great!
