Oil Pressure Switch Connector Wiring


Recommended Posts

Posted

Hi all I am replacing the oil pressure switch connector on a 85 GMC Sierra, the old one had 3 wires those will be easy to figure out but the third someone had run around the back of the enging and just zip tied it together with some other wires on the left side of the engine not connected to anything. Any Ideas anyone? BTW it is a 5.7L 350
