sounds like one hell of a truck! You'll have to forgive me, im new to the diesel game and I don't know a whole lot. What is this wiretap that I keep hearing about.

 

quite literally what it sounds like.

any fueling box that makes more than 65hp on a 2nd gen 24v vampire taps a wire on the injection pump to directly control the injection pulse signal on the injection pump via the fueling box.

the adrenaline uses a wiretap among its other connections to the truck.

there will be a wire going from the adrenaline to the injection pump...that is your wiretap wire...
