In 2015 they went to a new style coil pack (P/N:22433AA730) and the harness connector is different compared to the older 2013-2014 style. If you have a 2013 or a 2014 there are updated engine harnesses available to use the updated (improved) coil packs. The harnesses also have the improved shielding and grounding the 2015 and newer models got.
For 2013 models the updated harness is P/N: 24020AG620
For 2014 models the updated harness is P/N: 24020AG080
NOTE: There is no interchange between the old and new parts. For example, the new part number engine harness and new part number ignition coils must be installed as a set. You cannot use the newer coil packs with the old harness and you cannot use the older coil packs with the new harness.
It is all part of TSB #07-120-17R to Address DTCs P0351, P0352, P0353 and / or P0354
