Hello, I have a 05 Jeep Grand Cherokee Lerado 3.7. I got a new radio I wanted to put in. I got a wire harness adapter that fit but I needed to rewire the radio to the harness adapter. I may have blown something I checked the fuses and it was good and I replaced it to be sure. It has to be from in between the fuse and the harness. Has anyone else done this or know s if there may be a nother fuse in-between.

Are you presuming there's a fuse blown because the radio won't turn on? If so you should check for power AT the two power pins inside the wire harness that plugs into the radio to see if you are (or are not) getting power to those two pins. There should be a pin that is always "hot" and another pin that is only "hot" when the ignition key is ON. If both of those are getting power when they should perhaps something went wrong inside the radio.
