Hey guys, have a newer style oil pressure / fuel pump cut off sensor. I wanted to know if i could make that functional. I have rewired the fuel pump to run on a relay when the car starts, how would i wire the oil pressure sensor in so that it would cut it off when the pressure gets to low? Is this possible without hte computer?

You can wire the auxilliary oil pressure switch in series with the relay contacts. That will shut off the pump on loss of oil pressure. However, you'll never get a pump prime cycle and will get no pump power until you've cranked the engine a few revs.
