funky plug on Power Acoustik PT-566

I have two headrest mounted Power Acoustik PT-566 headrest monitors in my car.  I have been screwed with by the manufacturer for teh past three monthes, meaning they sent me the montiors but no the harness, I now have the harness and there is no black and red wire to connect the power like the ones I had before.  Now there is a red plug, that l assume is the power cable for them, because there are only three plugs one yellow (video), one White (sound), and one red (probably the power right).  Well I guess I shoudl get to the point, how can I connect the power with this funky plug?  It just looks like a smaller rca type plug, but is has a split prong on the inside, which is proabably that it is grounded in there also.  PLEEEASE HELP.  I have been waiting monthes and want to get this thing going. Any advice is helpful..  I wish it had one black and one red actual wire like my old one but it doesn't.  Thanks

I have not seen the power plug you are referring to. On Icon Tv's diversity antenna set there are 2 mini plugs and a small barrel power plug with no adapter. I had to cut the plug off and there was a red and white wire in the jacket. Red was 12v switched and white was ground. Remember most of this stuff is made in Asia and red and white are the usual power wires. Good luck

the plug that you are refering to should have a red wire and a black wire if so you are correct red (+) and black(-) good luck.
