Ive just brought a centre console with Aux and usb in the arm rest section all the wiring is underneath still but it doesn't have the wiring to connect it back up into the back of the cd player unit.

I am upgrading the basic cddj 600cd unit in my car to the silver oval 6000cds unit so that I can connect Aux.

Would anyone know what the part number would be for the wiring that is needed to run from the console to the cd unit? there must be a factory part i can buy instead of doing my own wiring as - i wouldn't trust myself ha!

Any help would be greatly appreciated.
