First: no matter where you post, put the SUBJECT in the subject line. The subject of this thread is "Explorer Radio Wiring", or something similar.
Second: have you tried the Ranger/Explorer BBSs like maybe therangerstation.com? Or downloading the '93-94 Ford Truck CD free from
here? Or a Haynes manual? Or an online manual? Al has links to a few online manuals on his
BroncoLinks site.
