Fuel tank selector switch
So my fuel tank selector switch melted today and I have no way to get into town because our lane is all snowed in (a good 3 feet). So I have no way to get a new part, and I was wondering if I could tie the wires for the front tank into an on/off switch that I have, because the back tank leaks. Just so I can at least drive into town. However, there are 6 wires that go into the switch and I cannot find any wiring diagrams on the computer. It is a 1990 F150 4x4 with dual tanks. Does anybody know which wires I need to tie into this new switch in order for my front tank to operate? Thanks a lot

The Front Pump is R; the front level sender is DB/Y.
(Rear pump is Br/Wh; rear sender Y/LB.)
Power to the pump is R/Y; the gauge is Y/Wh.
So to make the FRONT tank work, jumper from R to R/Y, and from DB/Y to Y/Wh.
