What kind of conduits are you talking about? Are you talking about stainless braided hoses, or some other type of thing? I got a set of braided stainless door looms with billet end caps from a company called autoloc, and they work pretty well. Basically, when you close the door, the stainless braided hose slides into the door without kinking. I saw they also make some modular contacts, and they're cool, but when you open the door the connection is interrupted. I guess they'd be idea if you didn't need power to the door when it was open.
