I have been working for the last 6 months on turning a 1989 Supra into a ChumpCar road racer. I only paid $1100 for the car, so you can imagine the shape it was in when I started

Of the gauges, the speedometer, the water temp, the oil pressure, and the fuel level didn't work. Fixed the mechanical speedometer with a new lower cable, the water temp with a new wire to the sending unit and the oil pressure with a new sending unit. This was after removing the aftermarket radio, aftermarket alarm, and about 50 lights that had been used to "decorate" the interior.

Still couldn't get the gas gauge to work. Took out the gauge and tested it: fine. Pulled the sending unit and it was flakey. Spent $150 on new sending unit and it still didn't work. Said screw it and went on to something else.

2 months later I am working under the dash and found a ground wire that wasn't connected. Yep, that fixed it.
