Hey guys, I didn't know quite where to post this. I'm doing an ls1 swap into my 89 firebird and I have a 98 camaro donor car. I don't want to use the 98 pcm and would rather use an 99-02 pcm. I've heard that you can repin the 98 harness to work with the 99 pcm. Is this true? And if so is there anything else I need to do to the harness or engine or would I just be better off getting a 99 harness?
