Try pulling the fuse. You should really try pulling the batt+ and hooking up the test light like I said, just make sure the radio fuse is pulled. You can clearly see a draw that way.

 

ok. changed the switch out yesterday and ran vehicle for about 20 mins at 3pm. at 8am this morning, vehicle started which it hasnt done in the morning. It did however turn over slow(like battery was low, but not dead this time). looks like there is still more to do with pulling fuses and such but atleast it seems its able to be driven without the worry of it dying on my while, lets say, going into the grocery store. Thanks for the help here guys. will keep you updated as i progress.
