It is certainly affecting the power top circuit. I have included other radio wiring diagrams as well as a diagram of the Instrument Custer. If you are blowing the Fuse #2 which is the 7.5 amp gauge fuse, you should look at the wiring for this circuit as there must be a short somewhere in this circuit. Again I would check any connectors you might have taken apart for the radio adapter and see if they are tied into this circuit. Maybe the radio adapter is faulty. I am sorry if I did but I may have confused you with another customer who is having similar problems after a radio and subwoofer install.
Let me know of anything that may have happened prior to this problem so we can get it sorted out. Still, don't discount the radio circuit as it does share some common wiring with the components that are not working.
