This kit will update all previous models EXCEPT the KN-8828 and the KN-8828D to KN-8828B-K+ (or KN-8828B-2K+ if the machine is currently a "-2" model) functionality. Includes everything as listed below: KN-08828B-2K+ Control Panel Two KN-8828B-2K+ K-thermocouples KN-8828B-2K+ Roast Chamber Rear Wall Left Side Panel for KN-8828B-2K+ control panel USB cable Solenoid drip cover Assorted replacement screws (not shown) If upgrading a KN-8828B or KN-8828P, we strongly recommend using the "-2" upgrade kit. The installation of this kit requires nearly complete disassembly of the roaster in order to replace the horizontal frame member shown in the photo. The roaster needs to be stripped to the frame and then the three main frame members disassembled. Before ordering be sure you are comfortable and sufficiently capable to complete this process. UK-105
