Lsxfox-need help wiring brake sw and tcc I need help wiring up the tcc wire and the brake lamp feed wire for tcc.
If someone can draw me a diagram to follow from brake pedal to relay I'd greatly appreciate it as I'm confused to high hell and my torque converter won't disengage

I don't understand how that kind of switch hooks up to my set up when my brake light switch looks like this

If you use that switch you would probably have to replace your existing brake switch with this one by building a mounting bracket for it and one part would work your brake lights the other part would disengage the tcc. Your other option would be to feed off of your existing switch to a relay that would be a switch for tcc. Check the fifth post down on this thread https://ls1tech.com/forums/conversio...witch-tcc.html it tells the wiring for the relay.

from what i can tell if the wires are clearly labeled the tcc should have 12v all the time like we discussed and when you depress the pedal it will remove the 12v and unlock the converter
the brake switch wire needs 12v when the brakes are depressed.
on the relay.....
pins 85 and 86 are brake switch output and ground like we discussed
pin 30 is 12v keyed power
87a(center pin) is for the tcc
87 should be for the brake switch
also check the relay you have, some 5 pin relays are a dual output(both are pin 87)
make sure yours is labeled with a 87a on the center pin
i believe this should solve your issue
