I guess UK3 is the leather steering wheel.
No where in the service manuals does it mention it specifically.
Sooooooo you need a 4 left and a 5 right molex harness to operate my steering wheel which means that you cant swap them out without updating your harness to the 6 left and 7 right M0lex Harness to the radio.
The weird thing is that it only shows one type of connector at the radio and that one is or the 6 & 7.
Maybe the end of the connector harness has both heads on left and rigt depending on your wheel.
I called the dealership and they are looking into it. Maybe there is a cheap fix?
Yaaa...i doubt it.
