What are these wires for?

[78SCRSMAN]

The car is a 78 SC with NONE of the extras, not even a power mirror. I've deleted the rear defogger, fog lights and headlight squirters too.

So, I've got these three wires but can't figure out where they go. I thought maybe they were for one of the switches for the above items but the diagram doesn't show them as such. Any if would be helpful. The colors are (WHT/BLK, WHT/GRN & BLK)

I also am not sure where to mount that relay in the photos, any ideas on that too?

TIA

I think that may be an intermittent wiper relay. I'm not that familiar with newer cars. Sorry I can't help you more

It is the wiper relay for sure, I just don't know where to mount it. Perhaps the fresh air blower housing?

Heater read window?

Defroster. Black goes on terminal one with the grey/green wires, white black on terminal two. but since you deleted the stuff it doesn't matter.

OK thanks crusty.

Any idea where to secure the relay?

The wiper box thingy goes almost smack dab in the middle of the car right under and slightly forward of the wiper motor.
