Alot will depend on what year truck you're working with. Pretty much any of them made after 55 2nd will have a provision for the squirters on the wiper arm bezels. You might have to remove a screw plug from the bezels. There should be a 1/8" tube coming from the botom of the bezel that will come out under the dash. It's simply a matter of running the hoses (I used vynal tubing) to the pump, then wiring up the pump to a switch.
