BLACK is ground , Red is for your gauge light so tap that into the dimmer or IGN pwr in the fuse panel. Purple runs to your 02 sensor ,splice it in.


umm for the oil pressure ive only ever seen them with 2 wires red/black and one for the pastic tube.Is your oil pressue gauge electric or manual? If its electric throw it in the trash because you will get the same reading as the factory.The whole point of a mechanical oil pressure gauge is to send oil right from the motor to the gauge itself so you get a accurate reading.Electric gauges have a sender that isint very accurate.
