2001 tahoe, visualogic screens

hello i am putting in 2 headrest from vizualogic in a 2001 tahoe.

my question is on the brains of the tv's there is

1- yellow ( constant

1- red ( acc ign )

1- black ( ground)

1- green ( parking )

my question is what do i do with the green ? should i ground it? has anyone installed this yet? also i would like to wire these to a rocker switch, which wire should goto the acc of the switch? is it the red one?

please help    thank you.

yea i never seen one either untill i opened up this package, it doesn't really make sense why they have it, the screens are in the back anyway. what would be the point of watching headrest tv's with the parking break up.

thanks for your help buddy.

k, i called the vizualogic tech.

he said that i do not even have to hook up the green wire. it will still work. he said that by law they must put that parking brake wire there because they sell sunvisor screens too, and they have to give an option for a parking break switch. because it is illegal to drive with a tv on on front of the driver.

hope this helps others too. :)
