I have a grey wire under the hood of a 1967 GTA fastback that I have no idea what it connects to. It comes out of the same hole in the firewall that my headlight harness does. Coming out of that hole in the firewall, I have my headlight harness, my harness that goes to my hood mounted turn signals, and this single, grey colored wire. It reaches the radiator support in length, has what appears to be factory wrapped insulation, and a single female bullet connector on the end. I've been told it may be the power feed to the foglights. If that is the case, what harness do I need to connect this grey power lead to the two foglight bulbs? Any help with this matter would be appreciated. Also, if anyone has pics of how the harnesses should be run, i'd really like to see them.
Thanks!

 

Not sure about the foglight harness. Try Mustangs Unlimited. They have good selection and prices. However, could it be to you windshiled washer motor. It is insulated and runs along the other, drops down to the pump. Just a thought.
