Cb in volvo fh4

Hello everyone looking for advice on fitting a cb radio in a 2014 globetrotter xl. Would anyone know if these are wired for a cb. I can’t find any spare wires at back or tachograph. I don’t think it’s fitted with antenna as I have 2 ariel on the roof one for radio I presume, the other has 2 small wires going into it. Any info welcome thanks

The guy at the fleece did mine about 4 years ago, he just scotch locked it onto the wires for the CD player, ariel was a small magmount with an adjustable elbow onto the slope at the front drivers side and the wires just fed through

Thanks for the reply scottie I was going to do the same joining into cd player but was told I would get interference. Also the wires going into cd player are fairly light and the wires going into cb are much heavier
