I have gone for the solution proposed by my friend swapping the red/brown with the blue/black on the black block connector as in picture above and it's working fine now. Maybe someone in the same situation might find it useful. Cheers

I was told just now by a friend to swap the blue black and red/brown wires between eachother. What do you think?

To this simple new radio unit

Hi there bud. I got a simple radio replacement but I don't have these red and yellow wires anymore. Which should I swap therefore, because radio is permanently on, causing central locking to not lock doors.
