Newmar doesn't always place it exactly where they say. On my DS, it was behind the dash, accessed by removing the panel above the dash.
Side Note:.....That KIB unit turns on the two cockpit lights and step lights when the door is opened or closed. It has a timer that turns them off after, I believe, 30 seconds. On my previous DS, I cut the power wire and added a switch. I wired it from the module to a blank switch location on the dash. This allowed me to turn the unit off. There are often times, like late at night that you may want the front of the coach to light up.
