Ok so I just received my summit EWP, the pump was supplied with a set of wires which also includes a fuse (see pic), I know nothing about wiring connection stuff so im planning to have an electrician to have it installed for me, im kind of confused, I read in some threads that a (Painless EWP Relay Kit) is required for the installation and I also read in some other threads that some have used the Air Pump relay for the EWP wiring connection, so I was thinking since my AP is already deleted why not use the AP relay for my EWP, I really don’t want to spend money on unnecessary stuff, just need to keep the installation as simple as possible,, so my question is do I need to order the EWP relay kit or will I be able to install it with only the provided wires ?
Thanx
Thanx

The relay is nothing more than a switch triggered by an electromagnet.
When the "trigger" circuit is energized, it flips the switch allowing current
to flow though and turn the water pump on. I use the fan circuit as a trigger
since it comes on in ACC (IE: key in and tuned to any position) as is easy
to find under the fuse box (big orange wire).

I do on the other hand have a question. As far as the fuse panel, which would be the best to tap into as for the switch source. Would that be any of the following( Radio, courtesy, pwr accy, or PCM ign. I just want the waterpump to come on when every I have the key in any position. What do you guys thing?????

Not sure about how this would work, usually if you do away with the air pump injection don't you get it tuned out of the PCM. Call me crazy but I think that's what I just had done when I removed all emissions stuff. Wouldn't that disable the wiring. I'm not trying to say it's a great idea but I just don't know.

I have seen people tap into the PCM/ign fuse or the fan relay for switch power. Still deciding which one I am going to use. Thing is IF the air pump relay will work, I won't need to tap into anything for switch power, the air pump relay would now be used to power the EWP...

Wasn't sure! Thanks but still seems like it may be a little work to use the air pump injection relay, may be I'm crazy. Do you just splice right into the lines in the back of the relay or what?

Still not answering the question, which actually fuse should I splice into in the fuse box???? I listed like four of them that I can think of that you can actually wire it to. Just wondering what everyone else would splice into!
