HUUMMMM, When I was working on my 2010 2 Dr Sport, I noticed when pulling out the carpet away from the rollbar in the rear " Right side" , there was a 4 conductor white plug not connected to anything. Noticed there was one wire a lot bigger than the other, almost for a pre-amp or something. If not for the pre-amp, than ???.
Sorry no pics, but if you roll back the carpet right where the hardtop sits on the body near the rollbar, you will see the connector I am indicating.
I already tried getting the Mopar Service book for my 2010 JK Wrangler, but not out yet.
