hey guys, quick question. i have an autometer fuel pressure gauge, the electronic 100psi model, with the sender and the wiring harness. problem is the harness cant be plugged into the gauge as it only has the 3 posts for the signal, ground, and 12v. so can someone tell me which color wire is which on the autometer fuel pressure sender? essentially ill just cut off the connector and just put each wire to its appropriate post on the gauge. thanks guys!

there are 2 different ends on the harness. the 3 wire end goes on the pressure sensor in the fuel line.

the other end should be a 10 pin harness with 2 rows of 5 on top of each other. there are 5 wires in the harness and the rest are blank slots

i got the harness, just need to know which wire is which so i can use my current 100psi autometer gauge. there are 5 wires, 1 red 2 black, one purple, and one gray. one of the black ones and the red are easy, they are for the power for the gauge and the light i believe. i need to know what the purple and gray wires are, and i suppose both black wires just get grounded, so the purple and gray are the signal? anyone?

Click to expand...

normal would be red = +12, black = ground, purple = switched +12, grey is sensor input. But nothing says they follow normal color coding of course...
