May some progress today. I found that the outdoor speaker wires exit the cab via a bundle of wires under the driver's vinyl step and then make a turn to the passenger's side and I lost it. If I can find the wires where they come into the passenger's side before going up, I could cut and tie them off from the radio and attach those going to the speaker switch to the cut off stubs on the back of the outdoor radio.
However, I know that radio is set up for 4- 40 watt speakers of which 2 are on either side of the radio under the outdoor TV. I will eventually have to pull the upper outdoor speaker covers and see what their wattage is. It may be a waste of time. For the moment, I can't play the outdoor speakers without blasting it inside. If I can switch it to the outside radio, I could play the radio or DVD and audio come thru those upper speakers.
Hey Joshua Cavitt, can you check and see what the watts are on the outdoor upper speakers??? Thanks!
