Has anyone uses an aftermarket fuel level gauge? I have one as I was sick of my speedo not reading I replaced all the gauges to aftermarket ones and they work perfectly except I don't know how to wire in the fuel level and autometer doesn't seem to be helping much. There are two wires and a reading between the two gives the correct ohms. The purple one is supposed to go to the gauge, where does the other one go? (MK3 Golf 96, was originally a gas car). I need help, cause one of these days I'm going to be out of fuel!
