F150 WIRING FOR THE FUEL SENDING UNIT

1993 Ford F-150

Electrical problem
1993 Ford F150 V8 Four Wheel Drive Automatic 94000 miles

I have a 93 F150 5.8L 4WD with a rear mount aft fuel tank. I droped the tank to replace the leaf spring hangers. The plug on the sending unit just crumbled apart as the tank was lowered. Now I'm not sure which wire goes on which post of the sending unit, and will the fuel pump work with out that plug just by snaping the end of the wires to the posts?

THESE ARE THE WIRE COLORS
2 wires are fatter than the other 2

The 2 fat wires= orange and the other is black (or dark brwn) with a white stripe

The 2 thiner wires= black and the other is yellow with green stripe

Hi dirtietruck,

Thank you for the donation.

Here are the schematic.

The thicker wires are for the fuel pump and they would work if you plug them in without the connector but ensure connections are tight as the fuel pump draws a rather high current and would heat up if connection is loose.

Orange = Pump Ground.
Brown/White = Pump power.
Yellow/Light Blue = Sender Signal
Black = Sender Ground or return.
