I will check it out today and see if there is a brand or part number and post it on here for those who may want this option

Hi folks, the little box I was talking about it actually the throttle position sensor, this could be made to work for a high idle. It is tied in with the transmission ecu and is an Allison part. possibly with a potentiometer or something to be able to adjust the voltage for rpms, there is a slotted cable end that is also adjustable. As stated in the last few threads it would be wise to tie it in to the neutral safety switch so it ONLY works in neutral. For those of you with older coaches this may be an option. Hope this helps
