DIY Lights on Warning Buzzer
Equipment needed:
? 12V Buzzer
? Cross head screwdriver
? Wire
? Small flat head screwdriver.
Process:
1. Remove the under dash tray from under the steering wheel. Undo all the screws around the outside with the crosshead screwdriver. There?s about five or six.
2. Remove the driver?s door switch. Easy, undo the single screw holding it to the body, then pull out. Be careful not to shut the door with the switch out, it bends it a bit. You don?t have to remove the wire going to the back.
3. Remove the heated rear screen switch. Set the switch to the on position, and lever it out from the bottom using the flat head screwdriver. There is a little slot for the driver to fit into. Again you don?t need to remove the wires.
4. Get your buzzer. You need to test if it?s electrolytic, connect the wires to something 12V, e.g. the interior light connector (take out the light and stick the wires into the red and brown wires on the connector) if it buzzes good, then swap the wires over. If it still buzzes then it will work however you wire it, if not then you need to remember which is negative, and which is positive. Do this by making it buzz, and the wire that is attached to the live is positive, and vice-versa. When you have determined which wire from the buzzer is + and which is ? remember them! They should be red and black, but you never know!
5. Attach the buzzer to the inside of the dash tray. I attached it to the far right hand side, but as long as you can put the tray back in, anywhere will do.
6. Take the wire from the buzzer that is the negative wire and route it to the right hand side of the car. You have to pass it through the sound deadening and into the cavity behind. You should then be able to pass it through the hole for the door switch. So, you know have a wire running from the buzzer to somewhere near your switch. Attach the wire to either, the brown wire going to the door switch, or to the connector that the brown wire connects to. As long as it doesn?t connect to the metal that the screw touches, it?s fine. Now pop the door switch back in and screw it up.
7. Take a wire from the positive side of the buzzer up through the dash to the heated rear screen switch. You need to attach it to the positive connector for the lights. To find this connector remove the switch from the plug, switch on your headlights, and get the multimeter out. When the meter reads ?+? 12V, then the red wire from the multimeter is attached to the positive light connector. Now attach the red wire from the buzzer to this wire, either, splice the wire on, or much easier, poke the wire through the hole on the switch. When you plug the connector back on, it will be fine. Stick the switch back in.
8. Reattach the under dash tray.
9. Shut door.
10. Turn on lights. There should be no buzzer sound, open door and buzzer will go off. Shut door, it will go off again. If you have a delay light it will buzz until the light goes off.
Let me know of any problems.
