Hey Aaron, you are right on both of the wireing plugs shown, the first single is the Anti-run on or deiseling solinoid it turns up the idle when the A/C clutch kicks in so the car does not stall but also acts as an anti deisel or run on so when you shut off the car it doesnt still try to run.The A/C is supposed to be turned off first before the car is shut off,as the clutch when engauged supplies power to the single brown wire/solinoid. that brown wire will also be part of the wireing harness in pic 2.on the TCS all part of the Smog/emmisions control junk.I have a carb on my shelf with that solinoid bolted to it still and the TCS on a bracket for the other side.....Darren.

the a/c will turn off as you turn the key off and let that solonoid de-energize.

if you have a turbo 400 there is a wire that lays on the left side of the intake for a elect. kickdown switch but most had the switch on the footfeet. i havnt looked to see what color wire mine is.
