stand on passenger side of car.. stick your left hand down into engine bay and stick a finger at 7-8 oclock on the water pump pulley. Feel that sensor.. that's your cam sensor. Now if wires got buggered.. it's likely over by the crank or just over the crank. You can pick up a harness off nearly any 3800. It goes from the icm to a connector right behind the icm, down to crank and over to cam sensor.
