  1. Hi just install a alpine head unit into my 2003 3.2 CL. I miss my steering wheel control and I was wondering what wire would I used if I purchase the PAC SWI-JACK steering control interface. I just need to know where the signal wire is located or what color is it? anyone? thanks a lot!

  2. I own a 2003 Acura 3.2Tl S , can someone show me where the antenna cable is attached to the stereo unit? I opened the required panels on the driver side and looked. It was not obvious.
    Thanks, Sergio

  3. I currently own a 2003 Acura CLS 3.2 with the stock Bose head unit. I am not looking to replace the head unit as of right now although i have ordered my amp and subs. My concern is, are there any audio outputs in the back of the Bose unit so i can run the necessary RCA’s to my amp? If not how can i install the amp without replacing the Bose unit? Any kind of help would be greatly appreciated Thanks, Bill
