Wiring a wiper fluid motor to a momentary switch

My vehicles washer fluid switch doesn't work anymore and a replacement costs $700 plus labor. I want to just skip all that and run a new switch to my cab. Looking for some advice on how to do that.

I couldn't find a place to post this in automotive, so I posted here. Any help would be appreciated.

From what I have read online, this is what I think would work. Please go easy on my newbieness... is that a word?

I purchased a piggyback fuse tap adapter (15 amp). Used my multimeter to find a "switched in" fuse location. Bought a momentary switch. Attached is my understanding of how to wire this set up. Please let me know if I'm missing anything.

Thanks,
Larry

That looks like it should work just fine. If you are using a fused tap off...... fuse it at 5A.

Make sure switch is normally open (closes when operated).

That will work, but if you can, trace the wire or find circuit diagram for the original switch and connect switch to that wire.
That will be cleaner and maybe even safer if done right.

Where is the best place to ground the pump? What gauge wire should be used?

Thanks

Connect the ground to any metal part of the body where there is a clean screw or bolt.
Use the same sized wire for hot and ground.

You can use #16 or #18 wiring.

Assuming you are going to bolt this pump to the metal frame of the car, I would put a ground wire under one of the mounting bolts.
