I am looking for a pcm pin identification.

You didnt specify an engine litre size? Anyway, the autozone site has free wiring diagrams. Some libraries carry automotive databases. One of the catabases you can access from your home computer. If you live in the area that the library serves, access is free. If you live out of area, you can buy access for a small yearly fee. I believe you can access mitchel, which is what we use here. You can access info for 1 model for 1 year for 20 bucks or less. Id have to double check that price.
