Truck is new to me. The 06 that is.
Given the power curve on the truck, it's obvious that it was tuned. I suspect the wiring is still on the truck but there is no display. how can I find out?
I also took two pictures of things in the engine bay that I have no idea what it's for ?
Any help greatly appreciated thanks
