Where do I find a switched hot wire on a 2008 Dodge Ram?
I've got a 2008 Dodge Ram 4x4 pickup, and I'd like to hard wire an after-market GPS system, so that the GPS comes on with the ignition, and it shuts off when I shut off the engine, the same as the radio or windshield wipers for example.
I have two cigarette lighter plugs, the left one does exactly what I need (the right one is always hot) but I can't figure out how to get at the wire and I can't find any other wires that are switched with the ignition.
Does anybody know how to find a wire under the instrument panel that is hot only when the key is turned on, or alternatively how to remove the instrument panel so that I can splice into the left cigarette lighter plug?
