6 wire waterproof connector for light

I have a GoLight that I want to hard wire to the top of the truck. But I don't want to have to mount or have the GoLight on the roof permanently. What I want to do is have the wires run to the top of the roof with a 6 wire waterproof plug so that I can plug it in and suction cup it to the top of the roof without running it through the window and using the cigarette lighter. Any suggestions as to where to find a 6 wire waterproof plug? I have found "waterproof plugs" already, but seem cheap and and dont think they will work because there is nothing to cover the connector when I do not have the other end plugged in. I would like to have something like a 5 way trailer plug that comes with the cover but can't find anything like it for 6 wires. Any help is much appreciated. Thanks,

What - no RF remote? I think it'll be tricky because of the high Amperage, but I wanted to advise against using a cig socket. Some cig sockets have troubles handling more than a few Amps and from what I see, a GoLight probably consumes upwards of 5A. Their instruction usually specify dedicated 10A fused circuits, thru relays etc. Hence my suggestion (as per GoLight instructions) to use a switch to energise a relay for its dedicated fused supply to the roof. The switch could be on the ACC circuit to ensure it's off when IGN/ACC is off. For the connector, I'd be tempted to use 50A Anderson connectors for the power feed, but if decide that trailer plugs & sockets are ok, why not use a spare plug as the cover when not in use?
