Mystery solved !
Thanks for the input.
I traced the wire which runs under the w/s rubber thru the bottom of the window post and to where the radio used to be (now in storage). I also noticed that there is no place in the dash for a speaker and the front half of the headliner is gone.
I read owners manual under the truck radio section that states "The full size Alnico permanent magnet speaker is mounted in the roof of the cab for increased sound performance required in truck operation"
Maybe not the reason, maybe the design engineers just overlooked needing a speaker location so this was the fix.I do know that the radio, heater,and clock were dealer installed options so w/ the wire stuffed behind the w/s rubber I doubt it they came from the factory prewired.
If anyone has pix of the headliner mounted speaker please let me know.
Thanks again.
