I figured the same thing based on the write-up in the KJ CRD section for installing cruise control. But the Cruise Control Store advertises that you DO NOT need to flash anything when installing OEM cruise control (see link below). Any validity to their claim?

How will the PCM know you added cruise control? That program is not installed,hence the flash is required.

I think the steering wheel radio and cruise controls are plug and play. My KK didn't come with cruise control, so I bought the mopar kit and it worked with no programming needed; I would assume the radio controls are the same way. The way I understand it, the switches only communicate with the clockspring, which sends the message out the the rest of the modules over the CAN bus. I do know you will need an adapter with the aftermarket radio to use the steering wheel controls unless the radio can hook up directly to the CAN bus.

This was the first thing I added to my Jeep and I can 100% say that it is plug and play (at least in my case). If you remove the steering wheel, make sure you replace the bolt that is used to secure it to the shaft.

Do you just need the above 2 parts & maybe a bolt?

Here are my tips:
1) Use a razor blade to cut out your hole on the steering wheel. It's only foam and very easy to cut.
2) The mounting holes for the switch weren't tapped. This was the hardest part.

Good luck.

Bought one of the rostra 250-9001 kits on amazon. Got it next day and just installed it, it was the complete kit switch and harness, only used the switch. Haven't gone on a test drive yet but with the ignition on the word cruise lights up by the odometer so I'm assuming its good to go.
It was easy but was nervous about somehow deploying the airbag, I disconnected the battery and waited a few minutes before taking it off. Thisvis the first car that I've worked on that had them.
