Mike-
Really appreciate your post, don't need it yet but in time I expect to. I have done latches and power windows on several other cars/trucks, and its nice to have your steps for my T&C when the time comes. You mention taking caution not to accidently activate the latch mechanism and let it crush your fingers because you left the power on. Why not simply deenergize the system by removing the battery cable or fuze, and eliminate the danger?
