I got into this when I saw a recent TJ steering wheel with cruise control go up for sale. The 99-04 WJ steering wheel was shifted to the TJ in 03-06. I am fairly confident the splines are the same, but I don't know if the cruise control and airbag are a straight swap. Does anyone know or have a WJ FSM? It would be nice to know since there are tons of WJ steering wheels with cruise control, but not many TJ's.
