Well, on the newer rams, (I'm not sure for 2nd gen) there's a plug behind the passenger side pillar with like 5 wires coming in to the adapter, and only 3 leaving to go to the computer and lights up top. One of the extra wires is meant for cab lights, and is already set up in the fuse box, so that it comes on with running lights. And you can just ground it to the top of the roof.
