Okay, a wire should run from one terminal on the back of the fuel gauge to a (Hot in ACC) wire. Another wire should run to a terminal on fuel sending unit(float). The remaining terminal should be hooked to a good ground.
Your fuel sending unit is much like a dimmer switch for a light. The more gas in your tank, the more resistance the sending unit will provide for the fuel gauge.
Okay, so accessory to one terminal, other terminal goes to fuel tank sending unit, other wire on sending unit goes to ground? I was looking through the schematics in my haynes manual, it shows that it goes through a little box on the back of the instrument cluster. is that not needed?
thanks for the help by the way, this was stumping me
Silly AJ can't you tell by the pics that Daves truck there is a super performance racing vehicle :thumb: :finger: . Wait until you see the gauge cluster I plan for the Blazer gonna use those 270 sweep gauges all made so straight up is hot straight and normal. Cause the blazer is a pre formance mochine :rotfl: :rotfl:
