i want to purchase a spare set of 4 sensors to install in my aftermarket wheels. i dont want to use the ones from my oem wheel because i will be using them in the winter.
1. will this part number work for a 2012 2500? 56029398-AB (found on ebay) http://www.ebay.com/itm/120893749920#ht_1501wt_944
2. do all these sensors run off the same frequency/signal, or would i have to have a dealer program them? if its a dealer thing, do they have to program them BEFORE they go into the wheels?
3. do they have to be programmed for LF, RF, LR, RR? or how does all that business work?
