Fuel pump wires 2000 XJ

I placed an order for a FSM and should get it in a week.
However, I would like to know right now the function of the 4 electrical wires going to the fuel tank with their corresponding color code. This is on a 2000 XJ.

Thank you

DarkGreen/White: 12V from pump relay
Black: Chassis Ground
Brown/Yellow: Sensor Ground (From C1/4 at PCM)
DarkBlue/LightGreen: Fuel level sensor signal.

Gesundheit!
