Looking for a guide for windshield wiper switch terminals

Post by JLT » Thu Jun 18, 2020 6:56 pm

I have a request for anybody who has a windshield washer switch for a 1971 bus lying around. (It's part #141-955-517, and was used from 1968 to 1972.) I don't need the switch itself, but it would be a big help to me if anybody had a photo or drawing of the terminals so I know which wire goes where. I'm afraid to unplug the wires myself, as I have a real talent for mixing them up.

I've looked on the Samba and elsewhere on-line, but I couldn't find anything like that.

And it would probably be useful information for anybody who's in my situation.

Thanks! That's just what I needed.

Now to make a tool to get that weird nut off. My old one broke.

The switch looks the same as the one that was used in the bus. I only note that the wiring to the fuse box changed from the 70 to the 71 model, at least in the bus and probably in the bug, too, if they used the same fuse box. So the wiper power wire moved from fuse #4 to fuse #11. I don't know why they changed it, but they did.

The layout of the fusebox was revamped when plug in relays were introduced and the electrical systems were getting more complex. Early bays brought the main electrical supply in to the hazard switch. Later bays brought it in to the unswitched fuses' buss bar (7,8,9) 11 is the new ignition switched-but-starter-interrupted terminal for headlamps, rear window defogger, and wipers
