Hotwire for wiper/washer pump

[JimKshortstep4x4]

The three wires hooked to the wiper button are all used for grounding. The wiper and washer pump are powered off of an ignition source so when the key is on the power is on.

To use the switch with your pump it would be a simple matter of running a hot wire off of the fuse panel. You can plug it into the "Unfused Ignition"
section and set up an inline fuse if you want to fuse it.

Then you could extend the wire for the washer pump switch to the new pump so that when you pushed the button the pump would work.

There are two wires on your original pump, 1 is power, (yellow, I believe ) and the other is the wire that you want to extend to your new pump.

I found that out by accident. With no switch and the pump tapped into the light blue wire both the wipers and pump were going with the key on. If the switch controls the ground, should I hook up the ground wire of the pump to the switch and run a hotwire to the pump? It seems to be doing something, but I won't know for sure cause I had to order a new switch because the made in Taiwan switch self destructed when I pulled the connector off the back.
Edit: Reread your post. So is the other wire on the original pump hot or a ground?
