I am building a stock ly6 1970 chevrolet c10. My ly6 came from a 09 2500 and I am wanting to use the stock fuel pump. Can anyone help me with the wiring? I have no idea what needs to be wired and where. I believe the green wire goes to the com but really not sure. Also do I need to run a relay? I just have about 6-12 inches of the stock harness that connects to the fuel pump.

Thanks for any help!

Out of the ECM, the Dark Green/White wire from Connector X1 Pin 50 is the power/trigger wire for the relay to control the fuel pump.

So do this.

4 Pin Relay
Pin 86 - DkGrn/White from PCM
Pin 85 - Black Wire to Ground
Pin 30 - Red wire from B+
Pin 87 - Red wire to Fuse Holder (30A) to Fuel Pump
