I don't have pictures presently. I can get them over the weekend (I know I already told you that - sorry - I'm lacking on follow through ;( )
There is an easy way to figure out which plug is for the brake lights if the lights are installed and functioning with a multimeter or test light.
With the switch installed correctly in the car - check continuity across the switch pins - there should be no continuity until the the brake pedal is pushed. The pins on the rear of the switch are for the transmission torque converter clutch lockup (TCC) . That part of the switch works in the opposite way - meaning it will have contiunity when the pedal isn't pushed. The white switch with the vacuum line port is for the cruise control.
The 3 plugs cannot be hooked up to the wrong pins by the design of how the plugs interface with the switches.
Another way to check the brake light switch, IF everything is hooked up electrically, is to use a jumper wire across the wires on the plugs. It's a good idea to use a wire with an inline fuse, 5-10 amp or so, to see which one lights up the brake lights.
If you need colors, then I can get that over the weekend for you - let me know. But it's kind of a pita for me to get pictures because my car has a cage in it making it difficult to access the under dash area without a little bit of disassembly.
