Gearbest Screen Help - just a yellow wire?

[cturts]

Hey,

My screen arrived!! It's perfect, I just need help now working out how I wire it only as I don't want to mess it up! ha.

So I'll be putting the 12v and gnd to the power strip? I've already read a few times in my searches that no need to mod this screen so is that right?
Then do I just do AV1? I read that it only needs one wire to the pi? I think sometimes I search so much I fry my head ha so all help appreciated I saw where the wires were soldered in Wermy's screen video, but can't work out if I need two wires to where he puts the white and yellow wires or just one, and in which order, one of the holes is circle and one square, would I ruin anything if I put AV1 in the wrong one?

Thanks!!

Solder your yellow wire here. Its not seen here but I always solder the groud wire to the pin beside the video. Seems to help with screen static. Wire the red 5v to your power source or power strip etc.

Ps you can use the white wire too...but you only need to use one or the other. It will default to whatever signal you have connected.
