What does this go to, not in the wiring diagram???

Power antenna.

Ah! Great!
The power antenna works so i guess they got power from somewhere else.
Does anyone more than me having a dual headlight relay installed? Its a square box installed next to the radiator.
Is this just the have all four as headlight (high beam)?

Looks like an old doorbell transformer...
Didn't know they had those from the factory. If their function are like what I installed on my '66, they would be installed to give your switch longer life, but the main advantage is brighter lights dim or bright, due to the function of the relay.
Then I need one for my house - doorbell keeps failing!
That is a headlight relay. Not a factory one though. Take the cover off and you'll see two relays, one for low and one for the high beams.
That is kind of an old piece though... I bought one for my '53 Windsor because it would look right with the cloth covered wiring. It's an Echlin (NAPA) part.
You may have issues with the headlight doors closing if using that relay.... There's a couple different fixes though.
but why did they use it? i guess the factory relay are broken back in the days mabey?
they have cut one of my red cable going to the headlight and going in to this instead

There was no headlight relay, except for the one that opens and closes the headlight doors.
There are a couple reasons for installing a headlight relay.aha ok, so they use of it is to???
im sorry if im not getting it
Headlights draw quite a bit of electrical current. The original headlight switches are OK, but they aren't as good as relays. The relay switches the heavy electrical current better and the headlights are brighter.
The other reason is the original switches wear out from this current going through them. It's hard to find good replacements. Using relays, the switch doesn't have the heavy current flowing through it and the switch lasts much longer.

Hail to Big John, Lord of all things electrical! Any chance you could show us mere mortals how to wire a relay into the headlight circuit? I'd like to add one to the vert.
I will do that. I'm doing a power window relay for my car right now.Hail to Big John, Lord of all things electrical! Any chance you could show us mere mortals how to wire a relay into the headlight circuit? I'd like to add one to the vert.

That was quite easy even for a novice electrician like me. I started from scratch rather than buying a pre-made harness to do it. I wanted the experience of doing it myself. Put relays on the Polara, Park Lane, and F100. No hurry for the other two Pony cars and besides tighter compartments mean I need to look around.
That's absolutely correct. It's a pretty simple circuit and the results are worth the effort.
There's been a bunch of write ups here and elsewhere on the subject. Some are pretty good, but there's a couple that I think could have been executed better. They all work though and they all are cheaper by far than buying a pre-made harness.
