Sending Unit Wiring & Replacement Connector
#1. My OEM connector crumbled and fell apart in my hands. Anyone know where I can get a new one? (NOT from a dealership) OR, is there a way to use bullet connectors to make a custom one? I have a 3D printer, so i just need copper that fits the lugs...
#2. I've found some information on which wire goes where, but not enough to finish the job. T = Brown = Ground To Frame G = Green = Connect To Fuel Gauge W = White = ??? >WHAT IS THIS FOR?< I'm rewiring the whole car from scratch, and using a cheap JEGS universal digital gauge display. So i need to know what each of the three wires actually do.

The white wire is for the low fuel indicator light.
Many parts dismantlers will sell you an original connector with a stub harness.

Yes, the white shorts to ground when the fuel level is low enough (on a stock tank, it is generally between 1 gallon and 2 gallons.)

Update: Not related:
My tank is completely empty, but the brand new sending unit I bought here from Pelican shows only ~35 ohms .... shouldn't that be reading as 60 ohms ???
