Hello,

Sorry for the wait. Are there 5 wires connected to the fuel pump module?

Customer: replied 1 year ago.
not sure i put the bed back on.
Expert:  Virtual Wrench replied 1 year ago.

Below is a diagram showing the wire colors for the gauge. I marked them with a red line.

Those are the ones you want to use. You should be able to find them in the wire harness going to the pump module.

Expert:  Virtual Wrench replied 1 year ago.

The color on the wire may be faded. Try and open the harness to see some clean wires and tell me if you find it.
