how do i hook up a solenoid switch on my 94 ford explorer 2wd?

so you want to replace an existing faulty soleniod with a new one?

or does it not have on at all? Im confused.

so clarification from you would help alot, then i can point you in the right direction.

well i put a new one on and didnt pay attention to the wiring and i hooked it up wrong i think

I found this wiring diagram. Everybody have a good day.
