I've tried reading other posts but can't find my exact issue on a 1991 fj80. Installing aftermarket radio with the Metra dual plug. The amp behind the glove box is gone and also removed the amp with the rear sub. I'm still blowing the fuse that controls the windows, etc. I cut the blue loop wire on the metra plug to see if that made a difference. Any help or link to a post would be greatly appreciated.
