I have an 02 Firebird in which I am going to either put an LQ4 in or have a LM7 5.3L bored out to a 6.2L to drop in.
I am wondering what wiring harness I need to use to keep everything as close to plug and play as possible. If I use a harness and PCM from an 02 Z28, will it work with either of these motors if they're from say 03 or 04? Will it work with an 02 PCM? Will it work with my gauges and would I need to change anything?
