This is a dumb question but I cant figure out how to hook up my fuel pressure guage I just bought. I followed the directions and it doesnt work.Has anyone hooked one of these up before? It has 4 terminals on the back, one is marked S and it has a resistor atached to it and the other side of the resistor is attached to a terminal on the opposite side of the guage that terminal has a I next to it right next to it there is a short teminal whick I believe is for the lights the I is right next to it and the fourth terminal is marked with a G which is the ground. Any help with this would be appreciated.

CANT ANYBODY HELP??????

signal, ground and you light (those two are right on the bulb i take it?)

Audacity, no they are seperate from the buld but you can see how they are attached on the back of the guage.

who makes the gauge???

gaffrig

Thanks Audacity those are the same directions I got with the guage and they dont make sense. The back of the guage looks different than the directions. I am going to call livorsi today. Thanks for all the help.

Most of gauges I've hooked up work this way..

S = Sender (connect wire that comes from your sender)
I = Ignition (provides power when key is on)
G = Ground
I agree the "short" one should be for your lights.

Cignificant is right. S = sender, G = ground, I = ignition. If the light is at the top of the guage, right should be to the light switch and the left terminal on the light should be ground. If it were a mechanical guage it would have a fitting for the pressurized line, Ignition, Ground, Light switch, and ground for light.
