From the pump there's a power wire that goes to a relay and a ground wire directly to the battery ground. From the sending unit one wire goes to the gauge and the last wire to chassis ground. My Dakota Digital module requires a separate ground wire from the sending unit to the module, which when i ran the sending unit wires, i was prepared for that. I shall use the regular ground strap from the hard line and sending unit by soldering my pre-run ground wire to the strap. It should be fine!
