Hi. I have a Grand Voyager LE which is the Canadian Plymouth version of your van. It has the Infinity 10 speaker system. I'm having difficulty following your description of your fuses. I'm using the Chrysler Corp. illustration of the fuse panel mounted above the driver's feet. The radio fuse should be in slot 11 and is a red 10 amp fuse. You should be able to interchange it with the left headlight low beam fuse which is in the next slot to the right - slot 12 - and is also red 10 amp.
If you're going to take the radio out of your van to test the wiring - and it's a relatively easy process to remove - I advise going to a wrecker and getting one from a '97 or later which has the cd player, if you don't have that already.
