run down on the car. 90 camaro rs. 305 tbi. project is instaling a lt1/4l60e. having a bit of the wiring issues here. looking at shbox i see cavity h in plug c230 <95 lt1> (automatic) tcc switched power feed. and i also see. cavity j (automatic) park/neutral feed from transmission position switch. where do these two wires go? thanks
below is the 90 camaro bulkhead bulkhead pinout.

I am not 100% positive on these, but here goes...

The park/neutral wire from the ecm should be org/blk. Cut the org/blk coming out of your shifter and splice the lt1 org/blk onto the half of the cut wire coming out of your shifter so the org/blk now goes from the ecm into the shifter. The p/n should be a negative trigger, IIRC.

By TCC switched power feed, I am assuming you mean the lt blu/blk wire coming from the ecm. If so, this wire will go into the car to the brake switch. Cut the purple wire coming out of the brake switch and splice the lt blu/blk into the half of the purple wire coming out of the brake switch, so the lt blu/blk goes into the brake switch. The brake switch signal is a positive trigger, IIRC.

Haha, not from England, I work at Jerry's Mitsubishi/Chevrolet. I copied the diagrams out of the factory service manual and faxed them to xomega. I just thought it was funny because the header on the fax said Jerry's Imports, and not Jerry's Chevrolet, it was kinda an inside thing that you had to be there.
