right now I'm doing a LT1 swap. I pulled the entire engine harness out with the pcm, and i am left with a connector under the dash that was part of that harness. I think it goes to the fuse box and everything in the passenger compartment that was associated with the pcm. Not sure and could use some help, if any one has a pin out for that connector or personal experience.

-Thanks

 

You're talking about the clear connector that the engine harness plugs into under the passengers side of the dash? The pin outs aren't very specific in the manual, they tell you the wire color per cavity but that's about it. They aren't really displayed on any ONE diagram. You've got the wires for the ALDL, Park/neutral input, VSS signal, and so on. They're scattered across several diagrams.

Has most every C100/C207

Yours is a 92 and most of my diagrams are built around the 90-92 harnesses. Each wire was traced individually through several factory diagrams to confirm the correct location and function
