Hi all just got myself a boost bus but the radio isn't saving channels etc what wires do I need to cut and join please as I cannot see the standard red and yellow if that makes sense

On Volkswagen you always had to swap over the red and yellow for aftermarket installs

Same 12 volts supply but one is permanent and the other is ignition switched
