This one is wired but a much better price. On amaozon.ca too for about $68 Can.
It says it uses 3M tape not a suction cup, so have to work around that somehow. It does say you can use another 12v source instead of the reverse light, so it stays on while driving. a reviewer says it has a longer wire than most but I didn't see how long (anybody know?) Can you make the wire longer if needed?--I see one set uses those old television/VCR plug -in type wires so you could add to those.
guidry, how did you run the wire for your set into the truck?
