I noticed when I bought my '73Z that there were two wires not connected to anything in the small branch harness that hooks to the distributor. The black one that attaches to the side of the distributor and the coil is hooked up of course. My question is. What is the black/yellow, and the green one supposed to be doing? I've looked at the schematic. I see nothing that has both wires. I can only assume that one wire hooked to something, and the other was for something different.

Any thoughts on this?

Off the top of my head, the oil pressure sender and VR condenser wires are near there, but without pics it's a tough call...

Was the car originally an automatic, by chance?

Doh! You said distributor, my mind saw "alternator" so Disregard what I said earlier...Although there is another condenser near the coil, but on my car (5/72) it's blue, not green. I have no Blk/Yel wire in that area--there is a yellow wire that goes to the temp sensor.

If in the past there was a Pertronix installed in your distributor you could have two extra wires hanging around in that area...

Is your ballast resistor installed?

Any pics?

I'll take some pics. As for wether or not automatic, I don't know. I'll see if there is any info on original title. On the schematic, I did see something about a passing relay having b/y wire. What is the passing relay?

Oh, yes, something else I can't figure out. On the firewall near the battery, there is a relay. It says made in france. It has a wire hooked to battery, one to a ground on frame, and apparently the one that would actually make something hot is not being used. As in no wire on the terminal.

Thanx in advance for the help guys.
