Here's an overview of all the components needed for the swap. On the table are the parts supplied by Dakota Customs, including the ECU, wiring harness, hoses, oil cooler for the power steering, and air box. The installer needs to supply the Hemi engine, accessory drive, flexplate, and bellhousing. The automatic transmission behind ’12-current versions of the V-6 can be adapted to the V-8 with the proper bellhousing. The ’07-’11 JK has a one-piece tranny/bellhousing, so it can't be mated to a Hemi, and that transmission wouldn't support Hemi torque levels anyway.
