Using the Speedhut (classic) gauges with the RF chassis harness. The pigtails that come with the gauges are two-wire (signal and ground), while the chassis harness is one wire (signal only). Since the RF harness already includes wires where I need them behind the dash and in the engine compartment, I'd prefer to utilize them rather than run the additional harnesses that come with the gauges. But what to do about the sensor grounds? Assuming the use of liquid thread sealant rather than Teflon tape, will the sensors be adequately grounded through the threads? Interested to hear what those of you who used the RF harness did to provide a ground path for the sensors.
Thanks as always.
