Purple Wire 4 TCC, How does the Factory Hook Up W/Cruise
The Purple wire to the computer from the brake light switch.
With cruise control does the factory use a special brake light switch?
Thanks,
Dave

I should double check first, however, I believe there is a separate switch for the cruise control. The the main switch handles the brake lights & TCC power feed.
The cruise switch typically has a vacuum line on it.

The car is an 1987 El Camino.
There are 2 switches, 1 with the vacuum line to it and some small wires.
The other is the brake light switch which looks like the switch that should be used in the Painless diagram.
The problem is that the brake light switch has 3 large wires at the front part of the switch which get power from the middle terminal to the outside terminals when the brake petal is pushed.
The back part of the brake switch has 2 small grey wires that do not seem to have any power or anything.
The car is a 1987 that had a 200 tranny in to start out life with, could those grey wires be for the TCC somehow?
Thanks,
Dave
