If you have an in car dvd player in your car and want to watch a movie or want to listen to some music, when you turn the ignition off, it is possible. Most car head units have two coloured wires, one wire which is the colour "Yellow", which is the wire that acts as a ignition live and the other wire that is the colour "Red", which acts as a constant live. If you car stereo turns off, when you turn off the car engine, then the yellow wire is not connected with the red wire on the wiring harness and are not connected together to the cars permanent live.
To make your car head unit turn on and off with the ignition off, it involves you to connect both the red and yellow wires together.
1)Remove your car head unit from the cars dashboard, using a flat head screwdriver, push it into each side of the car head unit and pull out the stereo, as an alternative to remove it from your cars dashboard, if you dont have din tools.
2)Once you have removed the car head unit, look for "Red" and "Yellow" coloured wires on the wiring harness.
3)Once you have found both of them, using a wire stripper, strip of 1 cm of insulation off the yellow wire.
3)Next connect the "Yellow" colour wire from the wiring harness, with the "Red" colour wire and using electrical insulation tape, tape up the exposed braid, this is to prevent the wire from touching other wires and causing a short circuit.
5)Push all the wires that are behind the car head unit, pushing them right back and then insert the car head unit back into the din slot, this is by pushing it in.
