There is a tow mode with some preset levels that works off EGT readings and boost pressures, and a performance mode that works off boost only. It can also display exhaust gas temperatures and boost pressure. To power the controller (which also feeds power to the pump and solenoid) we used the 25A switch on the stock dash of our Super Duty.
