Enter The Supra
I wasn't sure if there was a direct wire to the gauge from the sensor, but my ecu is not in the car along with the engine, tranny and main wiring harness. I'm swapping in a new fuel system and wanted to see what the fuel gauge was reading before with the oem denso pump unit, that way I can tell if the new unit is accurate. I figure I just connect my batter, but wasn't sure if this would work or cause any crazy, unwanted problems (like i dunno, airbags deploying?).
