I'm trying to wire up the pump on the intercooler so I can switch it on in the staging lanes. Do you have the directions on how to do it. I did a search and couldn't find anything good on here. they lost allot of the old stuff when they updated the site here.



------------------

 

I got my info from the PSP page I think? It is the white wire with orange stripe. Just do not hook up the switch to a positive. If you need more help I can run out to my truck and get all the info.

 

So where do I hook up that wire to.

 

You run the wire to an on/off toggle switch inside the truck, On the other side off the switch you run a wire to a GOOD ground. Keep the switch on all the time so the pump runs when the truck runs, the pump also runs when the key is turned to the on position, for when you are in the staging lanes with the truck off.

 

I don't have to run any power wires to the battery at all?

so I hook up a switch inbetween the orange strip wire and thats it? sounds to easy

 

what I mean is you splice the white wire with orange stripe or cut the wire and then use a wire nut or some other type splice to add the wire that runs to the toggle switch. nothing gets hooked up the the battery. It took me 30 mins to do the job. you can e-mail me at

I will send you my #. It might be easier to tell you over the phone.

Can you get at the wh/or wire inside of the truck, or do you have to do it near the pump?

 

I did it by cutting into the wireharness near the PCM.

 

Thanks
One more......where did you go through the firewall at?...by the throttle cable?

Thanks again.

 

Screw that wire out of the pcm crap. if you had searched for "intercooler pump switch" you would have found https://www.f150online.com/f150board...ML/008251.html

Which says the following
Well I'm bound and determined to get my intercooler pump to run in the pits so I copied Sals post about taping the white wire with the orange tracer that comes out of the firewall at the pcm. Removed battery and taped into wire. Grounded wire...nothing. Turned key to on and grounded wire..pump would run. Well I'm not going to sit with the key in the on position and not have the engine run so back to the pump.
Cut positive wire and run both ends to a single pole double throw switch. Connect pump lead to center of switch, connect other end coming from relay to one end of switch and connect other end of switch to positive power source. With the spdt switch there can be no back feed to relay. Even if you leave switch in power mode everything will work fine but if you leave it there and go to bed you're gonna wake up with a dead battery. Ran all the wire in plastic wire loom. Used a 35 amp heavy duty switch as I have no idea what the amp rating is of the pump. hooked up works great.
Incidently I hit or knocked the switch on getting out of the truck one nite and my wife says the next morning my truck is making a funny noise. The pump ran all nite long. The truck started fine. Must not draw much.

It is a very good idea to run your pump in the staging lanes as the fluid temp can easily go up 10 degrees or more when you shut off your enging and it DOES NOT cool down quickly. I do this all the time and in the pits until the fluid cools back to what ever it will drop to for any given day. Generally it will go up 10 degrees in a run. Ten degress of fluid temp can cost you .05 to .1 in et.

I AGREE...it will climb 10 degress and take for ever to drop...
