Wiring for the fuel sending unit

V8 four wheel drive automatic 94,000 miles.

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

These are the sire colors:
Two wires are fatter than the other two

The two fat wires= orange and the other is black (or dark brown) with a white stripe.

The two thinner wires= black and the other is yellow with green stripe.

Do you
have the same problem?

Hi dirtietruck,

Thank you for the donation.

Here are the schematics:

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 = Sendersdignal
Black = Sender ground or return.
