Since 99% of the wiring is already in a US-spec truck, how does the dash switch get connected? Is there already a hidden connector like the center diff lock behind the dash? Or do you need to make your own harness to bring down to the kick panel?
From what I can tell, the fuel level switch is no longer available. If no one has the template and the switch is NLA, could you theoretically just tie the wires together to fool the ECU into thinking the main tank is low and permitting the transfer?
