Aux switch wiring cables

[Chris6382]

I mistakenly pinched the battery wire that is part of the aux switch wiring found in the foot well on the passenger side. I was using this wire to directly hook up my two way radio when I noticed the wires, I then reconnected them with butt connectors the radio would not turn on. I checked all the fuses for the radio, and none of them were tripped, and then remove the radio and directly hooked it up to the battery, and it worked, somewhere between the radio in the wiring for the battery hook up there’s a problem. I don’t know if it could be the fuse and if it is, where is it? Secondly, if I blew a relay where is it not exactly sure if I’m on the right path, so any information would be appreciated. Thanks.

That would be fuse F72 – 10 Amp, located in the PDC. That information can be found in your owners manual under Auxiliary Switches.
