Hi everyone
i am trying to install a CB in my truck. Usually with the cascadia, you plug into the overhead compartment.
However, on this truck, there is no wire up top that connects to my CB. I was told by one CB shop that I need an overlay harness that I can only get from a dealer.
I have the Cobra 25 and two fiber antennas. Please let me know what else I need to buy. Thank you
