i wish it were as easy as those directions..but like i said the gauge only has these wires on it...and i found a daig. for it somewhere that expained it like this:
Red - 12v
black - ground
orange - signal +
brown - signal -
and the blue and white wires are signal output wires.
Those are the only 6 wires on the thing...theres not like a harness that has 4 wires on it for power ground and signal and another harness for the sensor...just those 6 wires like in the picture...which is what doesn't make any sense to me and where i keep getting caught up
