Do they make a wiring harness that is male that plugs into the female factory harness that connects to the A4 shifter as seen here? I ask because I'm hooking up a B&M shifter and would rather not splice into the factory wiring if such a harness exists. If not, I suppose I can just solder my own wires onto the back of where it plugs into on the shifter and make my own harness.

Something like an AC delco PT1556 but bigger: http://www.crateenginedepot.com/pdfs/Pigtails.pdf
