I had a problem with the blue wire for the fuel soleniod got it fixed, but next to it is a orange wire that is burned also that is in the same loom, but the truck starts and runs fine. Does anyone know what it goes to or what it is for?

 

i cant remember exactly what wire is what but the black wire is ground, the other two... one of them is hot (12v) with the key on, and the other is hot while cranking the engine, it is also controled by a relay directly behind the solinoid on the fire wall
