I've tried a search an only found results for the fords my question is did any of the LB7 trucks come with an high idle mode from the factory? If so I would I know or how can I activate it? And I've seen a couple of you tube videos of guys that have a high idle thats switched on by the cruise control but its the usual "my buddy did it I have no idea how or what he did to make it work just wanted to post a video of it" Its getting chilly here in the chicago area and it would be nice to have a high idle
