I have an 81 Camaro which uses a 2 prong oil pressure sender above the oil filter. I have just built a 75 350 which uses a 1 prong sender beside the distributor....(different threads) i'm just thinking of the easiest way to still use the stock gauge.
There is a plug where the oil pressure sender could go above the oil filter, but i'm afraid that it might break while taking it out, and also then i would have to find a plug to put in the other hole, just wondering about any easy idea's anyone might have
Thanks

On my 1980 and NastyZ's wiring for a 1978 there are 2 oil switches. The double prong is for the electric choke, one side is hot and with oil pressure it closes and sends current to the choke heater. And there is a 1 wire switch/sender to match an oil light or guage.
