ive been working on puttting an lt1 and t56 set up in my buddies 72 chevy truck and i need a little help with wiring. i need to know what connectors at the pcm are neccessary for the engine to run. im trying to eliminate as many wires as possible to clean it up. if someone can point me towards a write up would be great.

You don't say what year LT1, but my Tech Page has 95-97 PCM pinouts and such that you can look at. Basically, you need to supply all power and ground connections to the PCM and whatever sensors (some are necessary, some emssion items can be programmed out) that will remain functional.

the motor and trans came out of a 93 trans am which is why i was having some trouble finding a decent diagram to look off of

Somebody around here has some 93 pinouts, but I can't remember who.

I have a 1-page diagram out of a Chiltons for the 93 engine/ECM wiring. Not sure how accurate it is, but if you want I can e-mail you a .pdf of it.

I need to rescan.... they were too fuzzy to read at 200dpi. Do you still need them, or did you find them in the link in the post above?
