Rite now witch i am sure is correct

Black Ground
Red 12 constant
brown 12vConstant
yellow TV ign input
orange 12 ign switch
black/white ign switch but i need one that disconnects completely,



I would post on the12volt but they take so long. I have my 528T wired correctly. I know because I was able to test it on my power supply and it turns over like it is supposed to when. Black/white loses power. I take it to my car and set it up on my ext tv and it works but when I turn the ign off it does not switch over. I have it on a ign powered wire I got from the cig lighter. Now if i pull it off the wire it kicks over. It seams like there need to be 0 votlsor less for it to kick over. I dont under stand the same wire will cut of my tv but it wont kick over the relay unless i remove it like there is still volts in the line.
So my question is where can i find a wire that disconnects completely when the ign is off. so i cna use this as my black/white trigger besides the ign wire Im using now.

My 528t is set up to keep power to my tv for the few seconds that the car is running to on but not running when it normally loses power. It resets my tv and I have to start the whole process again to get back to the channel i was watching.
