My 02 came with a factory kit to control engine idle speed. It is still in the box and has never been installed. The booklet says that it is supposed to be used if the truck has items pulled off of the PTO on the side of the ZF6. Is there any advantage or will it have any use by installing it? The truck is a stock dually pick-up, and is mainly used for transportation, sometimes towing a trailer. I am thinking about installing one of those 12KW generators that pull off of the PTO. Thanks in advance.
