Is its switched +12V connected to constant +12V (as is its constant +12V input)? (I'm assuming it has both.)

What did you do for AC controls? I believe there is a common problem with that year and the AC controllers going bad and draining the battery. If you swapped out the AC controller it is possible that the replacement is bad. Ultimately you'll need to measure current at idle and determine if it is the radio or something else.
