Does anyone sell an adapter/wiring harness for the extra connector that goes into the stock Bose radio that you have to tap into to get the steering wheel controls to work with the PAC SWI-X in a 2K2 Maxima? I don't want to cut the wires that go to this extra connector because I want to be able to put the stock radio back in if I ever decide to sell the car in the future. What are my options to get this to work without cutting wires?
