04 rewire for 02 (to use COS5)

[Kevin Doe]

Has anyone rewired a 2004 PCM from a GTO to a 2002 F-body ECU to be able to use COS5? If so, I'd be interested in bouncing some ideas off you. Let me know if anyone has done this before.

Start by getting wiring diagrams for your donor car (2004 GTO PCM/harness) and for a 2002 F-body.

You'll need a "411" PCM.

I pm'd some people for advice.
