ben there done that
this is thew run down
there is no voltage to the sening unit
it works off the ground wires
its the resistance that makes it work
one ground goes to the spade on the sender and the other ground goes on the sender from a bolt or the ground spade[it doesnt matter] to the gauge
the power goes to the back of the gauge
it says power or ignition
the theres power to the light
thats it ground ign, light
and remember NO POWER TO THE FUEL TANK VIA SENDER UNIT.only ground
