So I’m finally getting around to installing my Midland MXT500 GMRS radio in my 05 TJRU. I’m mounting the radio on a Arizona Rocky Road overhead bar mount. I have dry fitted the radio on the bar and placed the bar on the roll bar. I need input on the wiring details. I pulled the glove box and loosened the fuse block. I see that there is a blank space for the #4 fuse but have not been able to figure out how to tap into it. Also from my limited ability to see the back how do I connect my wire to it? I can reach the fuse block without having to splice onto the factory pigtail. After unscrewing the fuse block I can’t get enough slack on the wire harness to get to the back. Is this the best way to get power or should I just bite the bullet and go through the firewall, splice the wires and go direct to the battery? I found the factory grounding point to the right of the fuse block so that should be easy. I’m planning on running the antenna cable through the firewall and mounting the magnetic mount with 6db antenna in the middle of the hood. I’m doing this because my area being the hot bed of crime I want to be able to pull the antenna when not in use. From what I’ve read the 6db antenna dies not need a ground plane. Your input is greatly appreciated. I’m doing a group run to Anza Borrego at the end of the month and would like to be able to communicate with the group.
