Hey alright well i know what i'm doing most of the time when it comes to installing anything stereo wise. But i just wanna make sure i know for sure, because i do not want to blow it. This is for a 7" screen.

I have 4 wires. Red,Yellow,Blue,Black

now when i look on the top of the unit, it shows

Red - 12v +
Yellow - 12v +
Black - 0v +
Blue - Earthing

that's only thing i'm confused about. is Blue the ground? since it's "earthing" if so what the hell is black.? lol

please help me out

you might need to add a diode in-line to get it to work. cut the original lock wire. solder in a diode to reconnect the wire. make sure that the anode side of the diode is facing the lock switch. tap your alarm unlock wire to the anode side of the diode. this should work.
