Need to power 3 more things.

I already have a p1900 for computer, monitor and hub . I guess I need another regulator. I was looking at the p2140 but seems like more than I need (feature wise).
I need to power a rear 12v camera, 12v 3a TV tuner and a 12V tv antenna. All items are in trunk.
I want to only run one power cable to the trunk for all 3 items. I dont want a timer, i just want it to turn on when car is started or car radio is on (first key turn before starting) and off when main car power is off without having a trigger line or usb(p2140).

do they need regulated power?

if not, then a simple relay is all you need to turn power on/off with the car.

well not sure....... The TV antenna is standard 12v and the rear cam is too.
The tuner is EYE TV 250 5v 2a.

What do i need?
Like i said I prefer one cable run to the trunk and split from there.
and want it all to shut down completely when car is off (no timer).

well you certainly will need a regulator for the 5V TV tuner, but the other 2 devices will probably be fine on an unregulated line.

do you already have a carPC? and if so, what power supply are you using?
