2004 F150 Heritage model. Had an after market alarm and stereo installed and the alarm wiring kept draining the battery. Mechanic traced the issue to the GEM module and said he disconnected the module which left me with no radio. Can the radio now be hooked back up without the alarm? Is this a big expensive job for a pro? I’d like to just hook up the existing radio again if possible.
