I have a 70 SS and some idiot put a 72 harness in the car, thanks to John Muha I figured somethings out. I need to find out why my idiot lights dont come on when the ignition is turned on, is there a difference? I have the engine out right now being rebuilt, but I am powering the car up to check the electrical system. everything works but the idiot lights, whats up with this, I NEED HELP! thanks steel

the idiot lights work off the ground
touch the wire that goes to the sender to a good ground and see if light for temp or oil comes on
alt light should come on if you hook up the alt
then make sure the alt housing is grounded
doesn't have to turn no motor needed
