Dakota Posted November 17, 2020 Share Posted November 17, 2020 Bought a used truck a while back and the fuel gauge didn't work so the dealer gave me a new sending unit. The new sender only has one wire going to the connector and one grounded to the mounting plate of the sender. The electrical connector from the truck has two or three wires to it and the sender has a connector that will fit it but, as said above, only has one wire from the sender to the connector. I can't get the gauge to work so I'm wondering how the sender works, electrically. If I ground that one wire directly, would that make the gauge in the cab register something? That seems to be the only possibility. Or did the dealer just give me the wrong sender unit? TIA, Steve Quote Link to comment Share on other sites More sharing options...
