ISX cm871/w PTO, cant fast/high idle

[jbird]

Sorry it took a while to respond, but i went by my mechanic and conveyed the information both Moose and Chamberpains supplied. He confirmed that he does use the insite software, and attempted each of the settings indicated. He even tried reinstating the fast idle portion of the regen swith on my de-mandated cm871. A Jan 07 14 post on truckers report says that the cm871 needs a optional hardwired switch to have that function work, but no part numbers were given and the Freightliner dealerships in Baton Rouge, LA and Lake Charles, LA have no idea. Any idea where i can find such a switch?
