I would like to operate my z1 with the steering wheel controls. I have the stw-ps ( not sure that's correct), but unless I'm blind, I don't see the aux hole on the back of the z1 that it plugs into! Also, what do I need to bypass my unit? I had instructions on a wire bypass, but my unit doesn't have that connector, I think it was connector 2?? I haven't tried the "flash" method, but from my understanding, it won't work since my truck has daytime running lights. Please help!!!
