Wiper Motor
I replaced the vacuum wiper motor years ago when I first swapped engines with the single speed wiper motor and linkage from my '63 parts car.
I bought a set of the Argentina repro wiper arms last year that suppose to fit the Falcon. The spline count was different than the pivot on the linkage and it broke the ends of the linkage while installing the arm.
While getting another wiper transmission at the junkyard, I also got a (2-speed) wiper motor and switch out of a '76 F-150. It looks almost the same as the 1-speed motor but this has the wiring harness made into the motor, on the 1-speed the wires have a disconnect connection on the motor, also the bell crank was a different length. I swapped the crank and ditched the one speed switch. I cut the shaft on the switch the same length to match the old switch after it was installed leaving enough length for the washer pump to work. Adding delay wipers will be granted by adding the control box between the motor and switch. The delay box and switch came off a '84 F-350. A trial fit reveals interference with a brace behind the gauge cluster using the larger intermittent switch. I took a angle grinder and flap wheel and made a flat spot on the switch to get it to fit. Take your time and use caution grinding the switch because the inside of switch will get hot while the outside stays cool.

Update- Junkyard wiper motor was on its last leg (weak), I had to buy one from auto parts store. The rebuilt motor comes with ends on the wires but no plug. I used my plug after carefully removing the old wires from the plug by releasing the retaining clip on the spade connector with a very small Allen wrench.
Here is a short video (442 KB) of the wipers
doing their thing.
'60 Vacuum Linkage on Top, 63 Electric Linkage on Bottom. The vacuum
linkage turns 180*, the electric turn 360* |
Orange wire goes to power, the other wires go to switch making it easy to
wire
|
The brace is in the way for the larger intermittent switch. I will
have to cut a notch out with the Dremel or move it with a hammer |
The knurled cap on the end (right) broke when installing the Repo wiper
arms |
Original is on bottom, notice the cover over the tension spring, spline
cut, and different rivet |
On the left is the intermittent switch, then the 2-speed switch. The tiny single speed switch on the right |
The black box will plug in
between switch and original wiring harness. Later model delay box is shown
(different plugs) |
The washer pump is from a '86 Volvo, I grabbed it because it looks easy to adapt to
anything with its own mounting bracket |
The wiper motor mounts to this plate and the plate is bolted to the body,
the F-150 mount is in the right, Falcon on the left
