What are these plugs?

[Russell]

Stripping out wires I don’t need and I know I don’t need these plugs and looks like they were never attached.
I could do with using a couple of the wires for other signals though and wanted to know what they would have been for.
The blue wire connects both plugs, then goes off to somewhere around the coil, other end into the plugs in the car.
The plugs themselves would have been near the alternator and fusible links.

The top plug in the bottom photo looks to be the same style as the headlight loom connector plug on the 280Z.
Does your car have a headlight upgrade?

Given where they are on the car, I suspect one is for voltage regulator and the other could be connections the to the windscreen wiper motor.

The windscreen motor uses 6 wires and is wired at the bulkhead.

Wiper motor plug accounted for. I thought something like voltage regulator but doesn’t match.
