Default 66 Engine harness - where's home for this wire ?

Don't know if these 2 black wires are correct on the harness or if Bubba added them ? Photos I took of the engine before rebuild show them going down behind the drivers side valve cover but I don't see any attachments for them there.

Can someone please clear this up for me ?

Thanks-

That area of the harness looks like its been "customized", possibly for ignition or instrument connections. Unwrap the wires and tell us what color they are.

Does look like shade tree electrical. Dennis

I would guess they go to the missing white resistor that is normally mounted on the firewall in that area.

First guess would be extra grounds someone added. Perhaps trying to fix a bad ground they could not find. Will they fit on a bell housing to engine bolt?

Those aren't factory wires - probably add-ons from a previous owner's alarm system or something. Unless you have factory T.I., your ballast resistor is missing.

Took the tape off the wires. They're black wires and 1 of them has a 3rd black wire spliced & soldered into it. The 3rd black wire is a heavier gauge than the other 2.

I noticed when connecting the starter/solenoid harness that there were only 3 wires going to it instead of 4. I wonder if the heavier gauge black wire I found under the tape could have originally gone to the starter/solenoid ?

The car does have a ballast resistor. It's not mounted in the right location. It's on the firewall on the passenger side of the distributor.

The previous owner told me the alternator was wired wrong by a shop and when he tried to start the car the harness was fried. He had to get a new alternator. Unfortunately he elected to go without a voltage regulator- the alternator he had installed only has a single wire going to it. So eventually I'll get a new harness, correct alternator & replace the voltage regulator. In the meantime I'll see if these orphaned wires will bolt onto the bellhousing.

Thanks for everyone's input.

I like the "Shade Tree Electrical" comment.

Ryan, If those wires are dead cap them off and hide the ends. You don't want the appearance of "Shade Tree Electrical". I wouldn't attach them to anything. Regarding the voltage regulator. Consider an electronic one for installation. No contacts inside, solid state electronics, same connections for installation and trouble free operation. Dennis
