Jeep Wrangler JK
Changes for 2015 include the new paint colors (including, new for 2015, Tank (dark olive green), Sunset Orange, Copper Brown, Baja Yellow, and Firecracker Red.) and trim packages (Sport, Willys Wheeler, Sahara, Rubicon, and Rubicon Hard Rock levels.)
Changes also include a new standard eight-speaker audio system, a new nine-speaker system that includes a subwoofer, a package that bundles steel wheels with 31-inch tires for Sport models, and a Torx tool set that's standard on all models, allowing owners to remove the windshield or doors wherever they are.
The 2007 model year brought a complete redesign of the Jeep Wrangler, and also a four-door model. The TJ chassis was replaced by an all new JK platform. This next-generation Wrangler was noticeably wider than the previous model, with a 3.4-inch (86 mm) wider track; and though the two-door model has a 2-inch (51 mm) longer wheelbase, it is actually 2.5 inches (64 mm) shorter in overall length than the TJ, allowing for a 44.3-degree approach angle and a 40.4-degree departure angle. With a larger factory available tire size of 32 inches, the breakover angle on the Rubicon is increased from 22.6° to 25.4°.

These vehicles do not have a switched 12v accessories wire in the factory harness. You will need to locate an accessories feed in the fuse box and wire up to the red wire in the APP018.
This does not retain factory amplifiers.
