TCC connection question Help...!! I know this has been discussed several times in here, but i cant seem to fully understand. I'm using a 99 camaro PCM and 4L60e....trying to finalize the wiring for the TCC. Need to know if the Blue 33 TCC pin is the correct one to run to the brake light interrupt curcuit and if so, do i just run the other side of the interrupt switch to ground..? And what is the other TCC pin for at Red pin 42 ? Also, what do you do with the 220 plug wires at position C and D....?
Any help would be appreciated guys..! Thanx in advance..!!! DK

Your correct that 33 on the blue connector goes to the brakelight switch, but the other side of the switch should be fused hot in run and start. The other wire red connector 42 goes to the TCC solenoid in the trans. You shouldn't have to do anything with it if your using a factory harness, it just goes from PCM to trans. Not sure what your talking about with the 220 plug wires C and D, could you be more specific?

C220 D = pin 33 blue same wire
C220 C = C105B, there should be 12V power to c220 C.
You should be able to hook C220 D to one side of the brake switch and C220C to the other side.
Red pin 42 goes directly to the transmission and you shouldn`t have to do anything.
