Wire from Ballast

[lazabby]

What is this black wire coming from the ballast? It looks like a ground and if so where does it normally connect?

[jmettee]

It's a ground that should run to your engine just right of your hand, under the bolt that would hold the Idle Speed Motor. You look to have a different bracket there, but I would use that bolt. As is, I think that is the ONLY ground path for that junction of wires at the attached end. I don't think it's redundant, so any of those circuits at the attached end may not be functioning correctly without that other end connected.

Yes, it is just a ground junction. You will need it grounded. The resistor block does not really need grounding but it was a convent location to make ground point.

Mine is grounded at the vacuum solenoid bracket.
