Has anyone installed the Edge Juice unit on a 4500 Kodiak? I am trying to install this unit on a 2004 LB7 Duramax. Edge told me last month that there should not be any problems. After buying the unit off the internet, the wiring plugs don't match up. Edge Tech is investigating my problem, but has anyone done this here? I really want the unit for the extra monitoring it provides and a little better MPG towing my 5th wheel. Not wanting to smoke my tires, too expensive for me. Please send me any info you may had on this installation. Thanks, John
