I've got three vehicles it will be used in. A 2002 Dakota Quad Cab, a 2008 Mustang GT and a 1991 Honda Accord (my daily driver). The RD powers up fine in the Dakota and Mustang but will no turn on in the Honda. I do know the cigarette lighter in the Honda works. I seem to recall reading something about lighters being wired differently than they used to be and that an adapter is needed to get a new RD to work in an older car. Am I crazy, or am I remembering correctly? I really need it to work in the Accord as that's the vehicle I drive for work and am in most of the time. I guess I could hardwire it in, but I'd rather just run to Radio Shack or somewhere and pick up an adapter if they're easy to find.
