Hey guys can some one help me? I have my ls1 fuel tank and racetronix fuel pump with the hot wire kit installed, when I turn my key the pump wont cut in, but when I by pass the relay the pump works, I think I need to change some wires for the original bulk head connector? I don't think there is any power getting to the relay, there's black,purple and grey wires on the hot wire kit, so I need to know what wires go with what? thanks in advance guys

 

Chassis Side:

Grey - Racetronix relay control. Use to turn fuel pump on and off. Connect to engine controller, terminal R9.

Black - Ground wire. It simply comes from the main ground terminal and is redundant. Probably used in a 4th gen car wiring harness but seems useless for us.

Purple (x2) - Fuel level sender wires. One needs to go to chassis ground somewhere. The other needs to go to your fuel gauge.

Fuel Tank Side

Red - Fuel pump power. Comes from the red power wire in the Racetronix harness that you connected to alternator. Hot when relay is closed, inactive when relay is open.

Black - Fuel pump ground. This goes to the large ground ring terminal in the Racetronix harness.

Purple - Fuel level sender wires.

 

here are a couple of pics, think I'm good now, thank so much QwkTrip
