installing wiper pump, which wire? Options

[914 RZ-1]

I'm installing a pump for the washer fluid instead of using the spare tire. I can extend the black/brown wire to the pump. Can someone confirm which wire that is?

I'd like to hook the pump up to the wiper stalk and not have to run a separate switch. I've read it can be hooked up so the intermittent wipers will run it. I have a '72; do I have intermittent wipers? I could not find any reference to them in the owner's manual, so I'm guessing I don't. I've included a picture of the wiper/turn signal assembly for reference.

How do I tap into the wire on my existing stalk?

I've read I can get a 911/924 wiper assembly and it will work. Is this true and will it fit my car? How does that option work?

Non of those wires if I remember right. The pressure from the bottle is released by a valve in there when you pull the stalk. I had bypassed that years ago with an electric pump and a button on the floor.

I don't know about the 911/924 stuff . . .
