auxiliry tank switch

my switch went bad and can't find a replacement. i bought a newer switch but figure out how to wire it ( if it can be done). my truck is a 1985 econoline f-350 the wires i have are 2- orange and red stripped, 1- black, and 1-brown. the new switch and harness has 2-reds, a black, and a brown and white stripped. the brown and red have jumpers.

i have several F150 switches that plug right into the 80-96 truck harnesses. here is what they look like. the wires you have on th enew switch are probably just duplicates for the black and brown.

for your situation. i would wire both reds to the orange wires one each. then both blacks to the single black and then both browns to the single brown.

one orange and red is hot i was figuring the other one is ground?

[fordman]

i wouldnt think one orange was hot and the other wasnt. i would test the wires in the van first. to make sure which one was hot or if both were. it could be a in and out too. hot in and the switch makes the other hot going out.

well i did what u said and it works. but, i'm back to square one.i had the fuel pumps replaced and the rear one is still not pumping. i can hear the front pump run but not when i switch it to the rear

check to see if its getting power to the pump.
