Video installation off of battery

[dipdog]

Hello. I have a video monitor that is connected to a video player in a Ford Expedition. I had both units, as well as a second monitor, wired to the circuit breaker. But I was getting feedback on the monitors, that only occured when one of the two monitors was turned on (feedback went away when this monitor was turned off). So I wired the trouble monitor directly to the battery, and now there is no feedback. My question is, is there some sort of switch that I can put into the electrical line of this monitor, so that the monitor will turn off when the car is turned off (so that I don't risk draining the battery if someone forgets to turn it off).

Thanx for your help!

wire the monitor to a 12v acc source

Do you know where I would find the 12v ACC on a 2000 Ford Expedition (Eddie Bauer)?

the gray/yellow wire in the ignition harness

Thanks again for your help!

Do you think that I'd be likely to have the same electrical interference that I did when I connected the monitor to the circuit breaker, if I connected it to the ignition harness instead (as opposed to the battery)? Also, do you know if the ignition harness has the only 12V ACC in the car (are there any other 12V ACC lines), and is it difficult to access?

it is not difficutl to access...if you continue to have issues check your ground...there are plenty of other acc wires in the car but the ignition harness is rated for the highest amount of current to run a tv
