Getting ready to put this back in the car before dropping the body. I do not have the vacuum door to worry about or need the washer. With that, what would I need to wire it up to a wiper switch? Second I will remove the vacuum and the washer motor is there a good picture of this? Also what is a tach solenoid Thanks and I plan to sell them

Jumper the limit switch if you don't have the plunger.


The tach solenoid operates like this: When you turn your wipers on power is on the yellow wire to the solenoid. When the solenoid is powered up it blocks the vacuum on hose "H" which blocks the vacuum on G and 10... When this happens the relay plunger drops (because vacuum is blocked), it drops and changes vacuum position on 6 and 9 which makes the door open up.

Make sense? If not post back again.

How the relay operates:

Thanks what I have is just the complete wiper motor and a new non OEM wiper switch nothing else. I will not use or need anything else since I have a long L88 hood and FIA Headlights. I was thinking the switch could be wired to the red wire and black to a good ground. Close?

If you are trying to eliminate the over-ride switch and the relay then wire the car up like a 73-76 wiper motor...

He's not here to answer you I'm sorry. I called Ernie and he said use the schematic above, it has your answer.

Thanks

Thanks for the help but my grey matter does not follow the above diagram. I will be using a aftermarket wiring harness and switch which might have a bearing on why I am not following the schematic. That said many thanks for the try.

Just watched one of your videos and I think I got it, it sucks to get older.

1968 with over ride light on. Wiper system does not work, disconnect the connector (black/red/white sires) to the motor. Override light goes off and I can use the wiper door vacuum override to open and close the door. The electrical override switch seems to be working as designed. Plug the connector back in and the over ride light comes on and door closes. Short in the wiper motor?? It's only a month old, got it from Eckler's. Did not have the problem before I did the water pump, may just be coincidence... Thoughts?? Thank you in advance.

Okay, After chasing down the wires, here's what I got. The limit switch doesn't seem to be depress enough. Maybe the tip of it rubbed down over the years, some times it works, some times it doesn't. Either way, when I tested it earlier this week, I used my finger, so it went down lower than the bracket holding it. Today, I was trying to use the bolt that's secured to the wiper door rails/hinges. That's a big piece of metal, so it's stop at the limit switch bracket, the button itself doesn't go any lower. After using my finger and screw driver to push it further in, everything went back to normal. So for the temp fix, I glued a little gasket material to tip of the limit switch, so far so good. Everything is working for now. If this pose is a little unclear, feel free to ask me any questions.
