Just completed timing belt change and have a left over electrical plug. A 12 inch wire with plug end coming off the drover's side top of rad. No idea where it goes. Note that the 2 A/C fans are on full speed all the time so must be source. Where does it go???

 

sounds like that connector is for the cooling fan switch on the radiator itself. look around the radiator for the mating plug, i'm unsure if it's at the top corner or at the bottom corner of the radiator.
