    Does someone have the diagram for the seprator. I need to find witch wire go's to the water light. There's three wires going to it and what they are for. And if I can wire up a new style single wire seprator. Like the 87's have. I have all the manual's but not the electrical ones.

    This is for 1990 vans, maybe it's the same?

    Thanks Cubey, but the 90 is a single wire hook up and the 83-86 used three wires and that is what I am looking for.

    Hope this helps, pretty sure the ground wire is the case being bolted to the firewall.

    Does enbody know where the fuel water switch is located on the 87 F250, it is the relay for the water in fuel light with a single wire sensor.
