On the bottom of the sensor there are 3 groups of numbers. Serial, frequency, model. You need to match up with common numbers on you existing sensor. All 3 will NOT match exactly. I asked a lot of questions. Wanted to make sure they were for the correct year, model, etc.

 

Hi - just putting this into the thread for informational purposes. This weekend I took off my Hard Rock wheels (stock KM tires and TPMS mounted) and bolted on new JL wheels with TPMS and stock BFG KO2 mounted. I did nothing else and when I drove the first time the display correctly displayed all tires pressure. All seems to be working without having to do any calibration or re-syncing. Just a bolt-on swap. Nothing more. Better lucky than good?
