Brake Pedal Switch Tampering. Help!!!

The previous owner of my '85 Suburban decided to install trailer lights himself :screwy:. In the process of doing that he screwed up all of the wiring. I fixed the turn signals but now the brake lights out. He jury-rigged his own wiring system and even cut the orange wire that goes to the brake pedal switch. :eek7: If any one knows where I could get a pictorial or schematic of the Brake Pedal Switch and the wires connected to it, or anyone who can e-mail me one at [email protected], I would be so HAPPY and can finally get the dang thing inspected.
