Review on 🔧 Enhanced Performance: Beck Arnley 201-0239 Oil Pressure Switch With Gauge - A Reliable Monitoring Solution by Jason Wright

Worked great on my 72' Datsun 240z. To check if it is a sensor or connector: turn on the key, unplug the cable from the connector and touch it on the ground. If the pressure gauge flies too high pressure, it is a transmission lock. If the gauge isn't doing anything, then it's a gauge. Don't leave it grounded for too long (more than 3-4 seconds) or you could burn your sensor. then you need both!
