What specially are you looking for/to do? Got a ton of crap saved on the 4.2 from the one we had.

need to verify all the fuel injector wiring before I pull the intake, if you have a pinout for the injector harness plug on top of the valve cover and the PCM connectors, it should be enough, if things are good there I will be pulling the intake
