The other day I noticed that the gray wire that you tap to the bump Is not hooked up to the back of the comp box Is every body elses that way or have I unhooked it some how.

 

So the pump wire is tapped, but the wire leads to nowhere? Yeah, to get the most amount of power from the truck, you need to have the pump wire hooked up... otherwise it can only make minor adjustments in performance.

 

Well I cant tell if I knocked the wire loose or if it can from edge that way. The truck still runs good and you can tell a significant difference between the levels. I guess I can solder it in and see what happens.
