Nice info, I may have to use it. Currently my steering controls don't work. Gonna try and remedy that when it comes out the dash next time. I remeber reading something about the negative wire being grounded or something and the controls menu in the radio should pick up on the steering wheel......we'll see
Here is a video about wiring a PAC harness to a Joying.
The same principles would apply to Seicane or Dasaita. And if the default harness doesn't work with the Alpine and/or Infiniti, it will definitely work with a PAC.
