Just picked up a '97 ZJ 5.2 Laredo that had the Infinity Gold stereo system. Head unit is missing and the factory plugs are cut off (hack job on the entire install-you should see how they cut everything up). I have searched and found diagrams that are only labeled by position in the factory plug from the harness but not by color of the wires. Sure I can test and find the ground wire and power wires in the harness but my tone generator will not let me test speaker wires because the Infinity amp is still inline and blocking signal to the speakers. Anyway- even knowing which is the factory infinity amp turn-on wire may help me. Thanks.
