oil pressure sending unit
do you need it sending unit plug in to run and drive the car? Im going do a swap to a aftermarket gauge that dont use a sender, just a line to the gauge.

Re: oil pressure sending unit
The car will most likely start and run without it if the fuel pump relay works, but it'd be best to keep it.

Re: oil pressure sending unit
That's the combined sender/switch, then. You could just leave it alone and put your mechanical gauge in the other oil port.

Re: oil pressure sending unit
The extra two wires are a bypass in case the relay fails during a run. It wont hinder running
