hi my name is ***** ***** i can help , you will need to remove the radio again to fix this , there are two plugs that are the same and can be plug into the incorrect place, one go into the radio and the other into the ac meter amp unit under the radio so just look for the two bigger plugs that is the same and swap them that should fix the problem. let my know and please rate the service before you go as this is the only way for me to get pay thanks.
