Good to know the JK and KK have the same accelerator plug
(I have both a JK and KK and couldn't be bothered checking myself, so thanks for letting us know...).
For now I have just received a Ram 1500 4.7v8 throttle boddy (with fly by wire throttle). Will be fitting this to see how much of an improvement it is over the stock one, then I might fit a ETC if I feel I still want sharper throttle response.
