Working on real 66 GTO under dash wiring. Trying to sort out original owners crap. It looks like a new under dash harness but looking at schematic some wire colors are not correct. I have the remains of a old harness and some wires are not colored correct. Especially heater control wires. On the ignition switch there are supposed to be 2 green wires on the ground spade which are supposed to go to water and oil senders. Not there. Do you need to buy a additional harness for the gto gauge package? Is there a under dash harness for a 66 GTO manual floor shift car with rally gauges that is simply correct and plug and play? And who sells it? Thanks
