where should I an wire electric waterpump for A/W IC

[juxsa]

I have an electric waterpump from a ford lightning that I am going to use for my A/W IC setup. I am just unsure of where I should Wire it up or how? I was thinking I might hook it up directly to the battery and running a switch to my cabin so I could turn it on when I was going to get on it, and so it was not running all the time. But there is that nagging feeling in my head that I would forget to turn it on or turn it off... So if I was going to wire it up so it turned on with my car where would I get the power from?

I forget the exact fuse location but a quick check with a test light will help you find key on power. Depending on the number of amps the pump draws you might want to wire in a relay.

I would definately use a relay.

Though I would find a way to make it run only when the engine is running. Maybe wire it to run with the fuel pump?

[juxsa]

so look in the fusebox for the key on fus and wire a relay up to that and the wire the pump from the battery to the relay?

[JamesL]

Pump - to ground, pump + to relay + output(87). Relay constant to Battery (30). Relay ( (86) to switched power (or run only power). I prefer negative ground switch so relay pole (85) to switch terminal 1 and switch terminal 2 to ground. flipping the switch activates the relay which sends battery power to the pump. I'd put the relay with the rest of the existing relays by the battery. You've got everything you need power and ground wise there.

[juxsa]

ok... so Pump - goes to ground
Pump + goes to relay would that be #87 on the relay?
Relay #30 to + battery or + alternator
Relay #86 to switch or what ever fuse turns on in the fuse box when I turn the key on. Maybe the radio?

Hows that sound?

yes, the negative wire on the pump can go to the block

yes, 87 is the output terminal on the relay

Yes

If you want to switch power then yes, put a switch between the 86 terminal on the relay and the switched power source from the fuse box or steering column and depending on how your radio is hooked up, that might be true also. Then attach relay terminal 85 to ground. I prefer to switch GND. If you switch GND and place the relay near the rest of the relays under the hood, you will only need to run one wire back into the car from the relay to the switch. Draw yourself a diagram before you start.

umm sorry did not read your post properly.

I would do a boost referenced switch going to a relay. say once you go above say 5psi it kicks on. Do it at a low psi so it does not heatsoak the ic.

[juxsa]

it would be super rad to put some kind of thermostat so that it kicks in when the water temps gets above a certain temp but I don't care that much. Does any one know if the ford lightnings water pump was temp controlled or was it always running?

I will have to take a look next week behind the fuse box to see how if I can just splice a wire from there to the relay

Summit and Jegs sell a kit to do exactly that and one that is adjustable for I think around 50 - has the sensors - relays and etc with it.

[juxsa]

you know what the kits might be called? I will take a look for it if I new what to look for. Those stores have so much stuff its hard to find things unless you know what it is.

Here is what I was talking about

Flex-a-lite 31147 - Flex-a-lite Adjustable Temp Control Switch - JEGS

fan control - JEGS High Performance

There are a bunch of other stuff similar that might work and are adjustable.

I am going to convert my omni to an electric pump but straight running all the time when power is to the key.

Hope this helps.

I think he is talking about running a water pump? You could thermostaticly control it. I'm not sure I've ever seen that or what the benefit would be other then not having to turn a switch on. I guess the car would warm up quicker.

Thanks for the input but I was talking about having the pump shut on or off. I don't think I am going to run a fan on the IC Radiator unless I really need to. And when I am at the track I was thinking about putting dry ice in my reservoir to get the temps down super cool

My bad, I didn't realize this pump was for an A/W IC. Dugh...its in the subject liine.
