The car is now coded for the combox to supply the aux so now you need
a aux cable that runs from the combox . Above is a schematic of the combox.

May not be away to code it back and run with the upgraded setup.
Actually I thought in most cars the aux always came from the TCU/MULF
or combox.

I have seen the cables on ebay for 10 to 30 bucks US.

Thank you so much for the input and the diagrams. Just coded out $6FL and the signal went to the head unit and not the COMBOX. Problem solved, thanks again.
