There is a major wire color difference in the wiring for the camaro and the 97 truck. I guarantee it will hook up and work right even with mismatched colors. If you get a chance, compare your pinout to a 2002 camaro pinout.

BTW, just for the hell of it do you have 2 connectors going through your firewall on the passenger side through the P100 grommet? I have a 3 pin black connector 2 grounds and one 12 volt and then a white connector that goes up through the dash back across to the drivers side. I didn't have to mess with anything in there since it was seperate from the engine controls. Thanks for all the comparisons.
