gents,

got a problem with the above screens.
i have to connect them to the powersource.
so i`ve got 4 wires red / yellow / black and a blue one.
the first three i can figure out
red : continous 12V
yellow : 12V switched
black : ground

but the blue wire can one of you maybe tell me the function of this wire.

thx

with a headunit, the blue is usually the remote wire, not sure if/ why you would need that with the screens in the sunvisors though.
thats all i know sorry

cos you wouldn't want them on when the stereo is off?

it might be one of those dumbass wires that connects to the handbrake, so they only show images when the handbrake is on. Of course, any earth will do


Try them before you fit them, try with the 3 wires connected, if nothing happens, earth the blue wire (will do no harm if wrong) and if nothing still, try some power into it?
