PAC SWI-JACK (steering wheel controls)

To maintain control of your aftermarket headunit via the steering wheel controls, you’ll want to install this PAC SWI-JACK adapter (at least for a Kenwood headunit). You’ll want to verify what adapter is used for your particular brand of radio since PAC makes adapters for various radio/car combos.

The info for installing the PAC SWI-Jack seems to be updated quite often. I didn’t want to get old data, but here’s a link to the website to get the most up-to-date instructions.
