Review on 🚗 Auto Meter Z-Series Electric Oil Pressure Gauge, 2-1/16" (52.4mm) - Reliable Oil Pressure Monitoring for Optimal Engine Performance by Tom Herman

Works well, easy to connect. I love having an oil pressure gauge on all my cars, it's a nice easy way to keep track of engine health. I had an adapter that came with the stock oil pressure switch on my LM7 5.3 and it fitted perfectly. It uses 1/8 NPT threads but every motor is different so just google your app. The sensor is a bit larger than I imagined, but I haven't had any issues with the gap. Run a cable from the gauge to the gauge and then take a fuse connector like this: https://smile.amazon.com/Support-Standard-Circuit-Holder-Socket/dp/B0146EB8EM Connect it to the ignition switch. Fuse next to the meter, run the wire from the fuse terminal to the 12V on the back of the meter. Find a hard, unpainted metal surface in your vehicle, attach a wire to it with a self-tapping screw and connect it to ground on the back of the sensor. I just plugged the headlights into the same sockets on the back of the meter so the headlights are on all the time when the meter has power, but you can unplug the headlight switch or your radio should have a signal that tells the headlights communicates. activated if you only want it to be lit at night.
