Question about fuel gauge wiring.
On the back of you instrument cluster there should be cir boards. The boards have pins that connect to connectors. The back of each gauge contacts the cir board.
This is the ammeter side of a 70 something but will give you an idea what I'm talking about.
You can trace out where each pin goes to
Each gauge (except ammeter) will contact part of the cir board that goes to the IVR
The cluster will either be directly grounded to the car body by it's mounting screws of a dedicated ground wire to the car body.
EXCEPT for the ammeter no wires connect directly to the gauge.
This is the fuel gauge side without the cir board the 5V mark goes to the IVR.
The F goes to the fuel sender
The T goes to the temp sender.
