Swapping red & yellow wires

[Anonymous]

Fitted new HU today and it worked first time - first time I have fitted one.

However the radio forgets its settings when ignition turned off.  It seems I have to swap the red & yellow wires.

Where do I do this? Do I swap them on the ISO connector or on the radio connector loom?  If the radio loom then it has a filter & fuse box on black & red wires so do I swap them before or after this?

Thanks
Chris

Does the yellow wire have a fuse? If so maybe you can just swap them over there. That would save slicing and splicing the wires.

Fuse is on the orange wire and so I have had to cut the wires in the ISO loom.

Wires swapped and all is working ok.
