one wire the positive wire goes to the fuel selector valve under the truck on the drivers side the other two wires are sending wires and head to each sending unit on the tank

I have a 78 f250 with twin tanks also. I've got my dash apart to rebuild the inst. cluster and install a CD player. When I get home, I'll look at the wiring and post my findings. Might be later tonite, though.

thanks

thanks i appreciate that those 2 wires have me baffled, I was wondering how did you install a cd player in your dash did you have to do any cutting or jsut modify the radio/heater bracket? and how did you wire it, to the fuse box?

I don't know if this will help as my switch has just one plug going to it. My plug has five wires in it, three on the left side and two on the right (looking at the connector side). Three wires from top to bottom are-light blue, orange, green/red stripe. Two wires top to bottom-brown/white stripe, red. All the wires go straight into the harness in the dash so I can't tell you where they go from there. The Chilton manual that I have only shows an orange wire from the fuse block going to the fuel solenoid. hope this helps.As far as the CD -yeah, Ihad to modify the control bracket with a new bottom half to fit my radio. I made it out of sheet alumnium and braced it to the ashtray bracket.
