I thought I would make a new thread covering my electric wiper installation in my deuce. This only covers the wiring portion of the installation. When I bought the A3 cab for my deuce, I noticed they just drilled a hole in the middle of the dash and ran the wires that way. Well I think that looked a little sketchy, not to mention possibilities of snagging wires. I routed my wires in the same fashion the air wipers were plumbed. I ran (2) 14 Gauge wires through a piece of 3/8” metal fuel line. This way it keeps the wires protected and routed nicely. The tubing bender I had was ok, but it did not work well on the tight bends. So I am not really proud of the quality of my bends. Maybe someday I’ll take it out and start over…. Someday. I figured the rest of the cab looks real good, so that should too. When the wires come out of the metal tubing, I also put on some heat shrink so the wires were protected better from a possible sharp edge on the tubing. Before I routed the wires in the tubing, I de-burred the ends of the tubing where the pipe cutter cut it.
There are 2 wire connections on the bottom of the switch. In the pictures, The one on the Right is Accessory/Ignition (depending on MV) or Battery Power. The wire on the left is what I believe is for the windshield washer pump. I know on the windshield washer kits, they only had a hand pump, but maybe I can find a 24 volt one somewhere. To get the windshield washer pump power to come out of this left side terminal/wire, the wipers have to be on and you have to push in on the knob. I was hoping I could just push in on the switch and it would run the wipers and put power to the wire (windshield washer pump), but it is not the case. Also in the original wiring harness was a ground wire. I found I did not need this ground wire to ground to the dash. It would have been nice, but I just made a small ground wire with (2) ring terminals that grounded the motor to the center bar of the windshield frame. It works very well and I did not have to run a long, ugly ground wire.
