93 YJ. Anybody ever try to use stock wiring and sensors to run aftermarket gauges? My temp gauge works, oil pressure gauge works, but works backwards. It reads all the way at the top of the scale when the motor is not running, but the power is on, then moves down the higher the pressure gets. I've tried reversing the + and ground wires, but that didn't help at all. Any clues?
When the tach is hooked up the needle moves to zero when it's got power, but when you start the engine it stays at zero. If I hook up the stock gauges they all work fine. Are the stock sending units not compatible with aftermarket gauges?
I have the factory service manuals with all the wiring diagrams to show me which wires run which gauges. Any ideas?
