So I found the draw. It was the aftermarket radio like I had suspected. I pulled the entire dash and all the wires then put them all back. There were two wires that were just sitting back there, loose, not connected to anything (maybe for the electric antenna that's been bypassed, which is also connected to fuse #2). I taped them up, put the whole thing back together and now I'm getting a .01 - .02 amp draw at the battery terminal. I'm guessing this is normal - does everyone else's have this much draw with the car off and the key out (guess it's the clock)?

Ricky, did you figure out where your issue was?
