Fuel gauge wiring

[OB6]

I'm not running the RF harness, but I am using the Speedhut Vintage gauges. For the two-wire fuel gauge cable, I was planning to run the black wire behind the dash to a chassis ground and the white wire to the sender. Will this be ok? If so, then only one wire from the sender pigtail gets used? The instructions seems to suggest it's ok. Just want to be sure I'm reading it correctly.

Thanks.

The sender needs a ground wire. Whether in the harness or grounded in place at the sender location. You said not running the RF harness. But for reference the RF harness runs a single larger gauge ground in the rear harness and everything routes off that where they split at the back, e.g. lights, pump, sender, etc.

Thanks Paul, makes sense, and based on that I'm all set. I have two wires run to the sender... one for ground to the chassis and another for the signal.

I need to stop thinking through these things at the end of a hot day in the garage. 😀
