Mystery Wire/Connection

[PCRammer]

Anyone know where this yellow-white wire is supposed to go? It is bundled with the tail light wires, brake warning wires (dual purple), and an orange-black that goes to the fuel tank. This is in a 71 and I've looked at the Seabiscuit diagrams and do not see it shown.

Aux gas tank???

That’s what I was thinking as well.
Does your Bronco only have one tank?
Usually the yellow wire goes from the tank selector switch to the Aux tank sender.

Look in zone H16.

I don't have a 2nd tank but it does appear to be for an aux tank. Thanks!
