I am in the middle of an LT1 swap from a 95 Buick Roadmaster into my 85 Iroc. I am having some trouble splicing the harness's together. I would eventually like to keep the AC and Cruise, but right now I am concerned with getting it running. I have found a lot of information about the PCM's and connectors for the F-bodies, but just a couple for the Buicks. My main question I have is, do all Lt1 computers have the same pinouts from the Buicks to the Camaro's. Also, when I read the wiring for dummies and worked on the car this past weekend I labeled the wires comming out of the bulkhead connector, but there are two power wires. Is one a supply from the battery, and the other supply from the ignition to the accessories? I was a little unclear on that. I am only home or a weekend once a month to work on it and am stuck so I would appericate any help from any of you that have completed the swap.
