Hi everyone. I'm new to the club and I'm hoping you can help either find a part or figure out the name of a part. This is for the 2001 Evolution E3

I'm looking for the part that has a big (larger than 3.5mm) aux jack on one end that plugs into the ceiling. Uses the same hole that you plug the light/fan into. The other end is an outlet that you can plug a cigarette lighter style charger into. For example your car cell phone charger would go into that end.

I don't know what to call this part so I'm having a really hard time even doing a search for it online.

Any help or ideas would be much appreciated.

Thank you.
