I am installing a second pump on my windshield wiper fluid reservoir to make a DIY intercooler sprayer. My question is, I have a 3 pronged toggle switch like the one below to turn the pump on and off. What wires go to what prongs? My guess is pictured below, but please tell me if I am wrong. Thanks.

 

call me nuts ... but do you always need to wire the middle prong?

Also, is the fuse box going to power the pump?



I always get a click switch (2 prongs).

 

I think the 'To Pump' And Fuse box are switched.

 

negative

 

i'm with drew, if your doing a simple on off ... why you need a 3 terminal? just get a 2 terminal switch

 

Yeah, I want to have the power come from the fusebox instead of directly from the battery because I think it's safer. I was only able to find 3 pronged switches at autozone.

 

What Jesse said...

That prong goes along with the "On" position...

 

So this picture is correct then?

 

Radio Shack homie. There's a wall of different switches. They're like $3 each.


Make sure to run an inline fuse.

 

Oh I see. But if I want to still use the 3-pronged, I can do the setup I originally posted right?
