A couple of wiring questions.

Where did you guys wire your TCC power?
-Dana @ LT1350.com said this wire should receive ground in park or neutral.
Where is the best place for this wire?

Where did you guys wire you Power neutral feed wire?
-Dana @ LT1350.com said this wire should receive 12volts when the brake pedal is not depressed.
Where is the best place for this wire?

Any help would be greatly appreciated.

Thanks,
Jay

Re: A couple of wiring questions.

Hmmm Im not familiar with LT1 wiring, but isnt it the ECM dealing with the ground/power to the TCC? I mean, with the inputs of other sensors (VSS, TPS, ...) it turns on or off the TCC? I beleive its wired that way on LSX's

Re: A couple of wiring questions.

I'm in the same exact situation. I can tap into the wires, but they're are in the interior. When I first got the harness, Dana said that I could get everything I need from the harness under the hood. So, If anyone knows, I'd like to hear the answer too!

Thanks

Whiteblaze,

On 89-91 Camaros you can wire the TCC up at the bulkhead(C100) purple wire pin E7.

For the PNP Signal I wired it up at the 15 way I/P connector(C207) to the black and orange wire. I can't recall which pin right now though. Or you can just wire it right up to the neutral saftey switch on the shifter.

Jay
