Missing relay or switch under hood

@rewilfert, that's a 3-terminal connector and is certainly NOT for a relay.  What it looks like to me is the connector for the external regulator for the alternator.  I suspect someone swapped out the stock alternator for an internally regulated one.  See if there's blue, black, and brown wires going to it and that will confirm.  If you do have an internally regulated alternator, it makes 14V-15V while running, and the 'L' light on your dash works, then it was installed correctly and you don't need to worry about this connector; all is well!

 

I went back out today and looked more closely at everything.  It appears that the plug had just been pushed into the area next to the 3 existing relays.  I looked at the wire colors on the connector and this is what I found:

 

I- terminal is Brown

D+ terminal is Blue (x3)

DF terminal is Black

 

This matches up with the wires to the voltage regulator on the wiring diagram.  This car has a newer alternator with an internal regulator.  I traced all 3 wires from the plug to the connected (and cut) wires at the alternator.  So, mystery solved.

 

Where would the voltage regulator have been mounted?  There is a spot on the inner fender just forward of the 3 relays where something was previously mounted with 2 screws (second picture).  The plug also reaches that location perfectly.

Yup that's where the stock regulator goes.

The component to the right of the 4 relays — it has yellow tape around its body — is the original regulator.

 

Your car has two abandoned screw holes where the original regulator attached to the inner fender.

Perfect, thank you all for the help in sorting this out!

I might as well jack this thread since the situation was resolved.
My high beams work when the lever is pulled back (as in to blink the high beams) but when you push the lever forward to turn the high beams on they don't turn on at all. Does this sound like a bad relay or high beam switch?
My instincts tell me switch but it would be convenient if it was the relay.
Thanks in advance!

So, you get the wiring diagram for your car, unplug the switch plug and test the continuity between ground and the on position using the wire color as your guide.

If the relay works for the momentary light flash, it should work for the full on. It will be the switch (or the wiring to the switch).

High Beam is up not forward??

[Bibm5]

This is what I was thinking. I'll dig into it once I get time. I was just hoping for an easy fix.

Hmm, up position is right turn signal on my car.

Later ('74 & on) had the high beam forward & "flash" pull back & down/up for the turn indicators. I have the same problem with my high beams on the Touring. I put in another switch and still have the problem. I gave up.
