Question about fuel gauge wiring.

This is helpful. Except that 'mating connector' is where the previous owner spliced a rats nest of wires to connect the after market gauge that never worked.

So if I attach a voltmeter to the side of the mating connector that leads to the back of the vehicle pin by pin one of those should lead to the sending unit correct?

If the wiring is still the original actual wire/ harness, regardless of connector, you should be able to look up "what the connector was" and get the wire color. I'll be back.........

Start with page 8-171 of the manual, they are calling this the (CB-1) the "instrument panel and body connector"

You can see that there is a G4 Dark BLue wire there and so that is the sender termination at the PC board.

THERE IS NO diagram of the PC board, but you can easily follow the traces to see where they go.

But..........that does not tell you the wire function, so now we find the tank sender wire..........and that is "CB-9" actually on that same page

So wire G4 and it's Dark BLue, so the connector pin is 2, but if the connector is gone, we at least know "dark blue"

Then we go find the cluster connector. "CB" is "Connector, Body", "CI" are "Connector, Instrument", and "CE" are "Connector, Engine bay"
