With a bit of research I determined that there are not less than 417 methods for installation of an electric windshield washer pump. After full and due consideration to each and every one, it was determined that #295 was the best for Viole and me. YMMV:

I started with a tank, pump and wiper arm sprayer manifold system from the local Pull & Pay. Note the tubing on the wiper arm leading to the spray nozzle:



I added a standard automotive relay from AutoZone, fastening it with the upper foot-pedal mounting screw:



I removed the yellow wire from the foot switch and connected it to the output (#87) terminal on the relay. I spliced into the purple wire on the foot switch and ran that to the relay power input (#30) terminal. From the original yellow-wire terminal on the foot switch, I ran a wire to my pump and to the switch input (#86) terminal on the relay. A ground wire from relay terminal #85 completed the wiring and the project.

The new diagram looks like this:



Works great! A momentary depression of the pedal activates the wipers for a cycle without spraying fluid on the windshield so it is still usable for demisting.

HTH someone....

My use of the foot sprayer usually shoots washer fluid over the car at some point! Cool upgrade! Thanks for posting.

No po

Viole will only ever have one PO - I'm her second and final owner! Seriously, though, this procedure is completely straight forward and documented and could very easily be reversed.

When ever you do things like that..your called the PO from hell.:cool:

Overspray

The wiper arm mounted sprayer nozzles would probably work quite well with the foot pump. Hmmm, I might just try that....

Is that simply a delay on relay?
I like your approach, and it seems pretty reversable...for when your grandchild inherits the car, removes your comfortable Eclipse seats, and repaints it the original color.

Delay

Nah, it's just a delay in the fluid getting through the lines by the time the wiper motor comes out of park and initiates a cycle back to park after releasing the pedal. (Folks with a heavy left foot might have trouble with that maneuver....) :) But I like the idea of a delay in the circuit! I'll have to play with that and I'd bet Radio Shack has something that'll work. It would go in the pump circuit, though, not the relay as the relay operates the wipers and the pump comes off the original foot switch.

I was planning on being buried in the car but I guess I should at least consider the possibility that it will one day be restored to it's original glory....

I'm definitely NOT the "keep it stock" police, with total respect to those that are.:beerchug: I would keep a pristine, or rare auto in stock condition without hesitation. My electrical basketcase, multiple repair panel replaced, Bondo laden car that I purchased will be rebuilt to my specs.. I am keeping track of my Frankenstein documentation also.
Again, thanks for sharing a good idea.

Nice........the only thing I would do differently would be to mount the relay up inside the dash somewhere, it would make the install look a little cleaner.

I saw the up-inside-the-dash-mount technique used in method #56 and decided against it because it would take more time and effort than I wanted to expend at the time.
:)
Actually, I just picked up (from the local Pull & Pay) a small under-the-hood relay/fuse box that I plan to use for this circuit, the "Otto start" and others as they occur to me.

does a foot pedal activate the washer motor? I have an aftermarket kit but I'd rather keep it stock if I can figure out how to get it working:banghead:

Your foot pedal operates the wipers for a few swipes then shuts down, ( delay wipe) or you can hold it down and it will keep going. I removed the rotten bellows in the pedal and installed a momentary switch, with a elec. washer pump., Touch the pedal and get the wipers to wipe, push harder and the washer fluid will spray at the same time .:yup: OGTS sells a Chilton's manual for the GT that is very helpful :yup:

they have a Chiltons manual? i havent been able to find one of those in years. is there a switch to turn the water pump on or does the pedal activate the pump?

duh! now I get it the bulb squeezes the water( no stock pump)?

actually if you put a diode on the yellow wire, and add a wire coming off the foot switch, the wiper motor won't feedback to the pedal, and the original foot switch works fine as is, you don't need a relay. I do sell a kit, with an electric pump and switch with plug in diode for $45. No soldering.

Yes, the original switch on the original foot pedal activates the washer pump motor. The first post in this thread includes a wiring diagram and text explanation of which wires need to be moved to work with the relay...

Just another approach for an electric washer pump location. There is just enough "flat spot" room for the 5/8" hole on the bottom of the original washer bottle. Needs to mount on the clutch cable side of the reservoir. I will post a photo of it in the engine bay when I am actually done with the installation. This is a mock up with a spare bottle. wash bottle mock up.jpg
