Review on Factory Auxillary Adatper Mitsubishi 2003 2012 by Abdulkarim Sugge

This adapter has three metal pins that plug into the back of the factory wiring harness in the three locations indicated in the instructions. You need to find them online, I found links to them in one of the comments here. They are not included. They are thin and not very easy to insert. At least not in my case, but it could only be manufacturing tolerances and material temperatures that could cause you more or less problems. After installation, you have a two-piece cable. The terminal cable ends with an RCA set. Then there's the RCA to 3.5mm jack adapter. This plugs into the headphone jack on your device. The sound quality is mediocre with this setting. The 3.5mm side has a large diameter insulator that got in the way of my phone case. HOWEVER! Get Marine Bluetooth Module! You can remove the 3.5mm adapter and turn your stereo into a Bluetooth receiver. Works perfectly and the sound quality is much better. I bought this.
