Radio Harness

My Dad drives a 2003 Freightliner Columbia Class, he is installing a
JVC KD SHX850 radio.

He doesn't want to have to cut into the factory wiring harness. I am trying to find what aftermarket radio harness would fit so he could cut into the aftermarket harness instead.

Anyone have any ideas. I have tried googling but have come up short.

Thanks

I may have to call a freightliner dealer. I live in a very small town so we are lucky to have a radio shack. Radio shack is not what it used to be with all the little odd parts a person may be looking for. It has seem to become more about TV's, phones, and like items and less about individual parts. You used to be able to go in and get coax by the foot that was great for cb connections (it was grey), not anymore though.

I'll continue to google and maybe get lucky. Sometimes that is all there is.
