Not bein an ass, but can you explain in detail.....I get very confused with electrical tasks.there should be a trigger wire for the relay. just put that to a switch. thats how i did my airdog on my ford.

whats the difference between doing just a inline switch compared to a relay with a toggle/switch?Just put a switch rated for the amps the pump draws inline on the power wire that goes to the batt. Or do the same thing but using a relay inline and run a simple toggle switch to the relay.
Relay allows u to run smaller gauge wire into the cab and use any type of switch u prefer. A simple switch is easier but larger gauge wire is needed and less options for switches rated for the amps. Personal preferance is kinda what it come down to.
