Mounts on the bottom lip of the dash below switch. Behind the dash where you can't see it. One screw.

Not sure - my truck doesn't have intermittent wipers; I've got that post tagged in my "watched items" on ebay but haven't done the conversion yet myself. Maybe Bill's got a diagram?

There is a module besides the switch. These are the parts you would need, though you can probably find them cheaper at a junkyard:

Wiper Delay Switch Ford Pickup Truck 1973 1974 1975 1976 1977 1978 1979
| eBayThis set up is from a 1987/91, not 1973/79! Seller probably assumes that potential buyers will think E7TZ refers to 1977. It does not!
1987/91 F150/350 & Bronco intermittent wiper governor ID engineering number: E7TF-17C476-AB or CA
This ID number cross referenced to part number E7TZ-17C476-A which was replaced in 1989 with E9TZ-17C476-A

I noticed that, but pretty sure I've seen threads with people here using modules from that era to retrofit intermittent wipers into '73-79s too. He's not selling as factory original number-matched parts, but as a conversion "kit" to upgrade. I don't know of any reason it wouldn't work in that regards ... ?

From reading other threads, the later-model switch/governor will work as an upgrade, just may need to swap a wire on the two-wire connector to get the washers working:

I think I'm gonna do this myself while I've got my truck's instrument cluster out to get to the wiring anyway.
