I have a couple of units to go in the car
1. Signal Booster
2. 2x 9" Headrest Screens
All of these just have 1 Red & 1 Black wire.
What would be the best way to connect these?
straight to the battery or connect the red to ignition?
Basically I didnt want something like a screen be left on by accident and come back to a dead battery? or cant that happen if the key is not in?
**Also anyone know the best way to get a wire through the front seats? for the screen wires...**
