What is this?

I have the engine out - in the machine shop in preparation for a 445 build I'm doing, and looking over the engine bay thinking about simplifying the wiring and the new fuel line configurations and I was wondering what this is. I'm not even sure it is original equipment. It is connected to what I think is the ground side of the starter relay, but nothing else.

Any guesses?

Voltage regulator without the cover. I think your year had one with a plug-in connector.
Was the alternator upgraded to an internal regulator?

Alternator Voltage Regulator

D4TZ-10316-A (replaced C3SZ-10316-A) .. Alternator Regulator / Replaced

Applications: 1963/64 Thunderbird; 1965/81 ALL.

In 1982, Ford replaced this points type regulator with an electronic regulator (E2PZ-10316-A). There is no modification required to install it on previous years.

In 1990, Ford replaced E2PZ-10316-A with: FOPZ-10316-A (Motorcraft GR-540-B) / Available from Ford.

The cover with the points type regulator may have dents in it, because...

When the points got stuck (very common), people rapped on the cover with their knuckles, screw driver handles and etc. to unstick the points.

Thanks Bill, I am assuming I can remove it because it is not connected to anything other than the starter relay, as can be seen in these better pictures. I have not changed anything in the electrical system, but I am thinking about going with a one wire, or self exciting alternator to clean up the wiring. If it is not needed the next question is, anyone need one?

After another look ...it looks like a relay of some sort. AFAIK regulators didn't have fuses. Then there is the cover that says fuses underneath.

I think it is a voltage regulator but an aftermarket one for some aftermarket system originally installed by PO. Then most of it removed. Like a second alternator powering something added on. Is there any signs of anything installed then removed? Generator, winch, 2nd alt brackets, 2nd battery, etc.

I took it off, it doesn't have any Ford marks or any part numbers. When I bought it the truck had some evidence that it may have had a plow at one time. Perhaps it was to control the plow lift or lights.

I had the restoration done by someone else, and he probably just re-installed it. It was attached to the positive side of the starter relay, but nothing else. Just part of my under-hood clean up.

Well, if anyone needs one, it's yours for the postage! I plan to change over to a self exciting alternator, still considering a 3G set up, but I like the 1-wire idea.

I have lots of time to consider it as next I'll be running a new fuel line.

Control relay for something.

My guess is the wire from the battery is the common power to the points. One set of screws is from switch(es) to energize the coil(s). The other screws are the output power. Very 1970's looking for sure.

Wonder if it had a cap/camper on the back at one time? Off road lights?

It's a current metering and switching device.
