Radiator fan pulled a wire from its original emplacement. Can you help me to find out where it goes ? This wire is gray with a yellow line. It is connected to a small can (size and shape of a coca cola can) fixe on right top radiator inside shell. Probably related to the A/C because i have to a/c anymore. The other end of the wire is a flat terminal with a plaric square casing. Truck is a 1989 e350 diesel with a 7.3 engine.

 

no idea....it could be a ground wire...but I doubt because usualy they are black....but try grounding it out anyways and see if your a/c works.
