bought a liberty wagon gen 1 and it has been converted to manual, it still has the auto dash with the auto gear icons in the middle, there are a few concerns i was wishing to get addressed by people who know. so any feedback would be much appreciated

1. should the cruise control be affected by the change of transmission as the cruise lights up on the button but does not work
2. should the revs be affected by the change? say if it has an auto ecu still or something like that? because it revs a fair bit over 3000 in 5th at 100 my old mans fwd same model more kms revs at about 2800-3000.

thank you for any feedback!
