IC pump

how do you check to see if its working correctly?

If it is hot-wired you should just be able to turn the key on. This is really the best thing to do. Check the SyTy Readme for instructions on how to do this.

I'll spell it out for good measure.

Ground the yellow wire coming from one of the two relays on the firewall. with key on, the pump will come on. you can hear it.

otherwise, jumper the aldl connector just like you would for checking codes, the pump will activate then.


Or, try running the truck so that the engine temp is over 180 i believe, then remove the cap to the intercooler, you should see some kind of movement
