kill switch 5th gen honda civic

For this one you need a normally closed push to open switch. I found a brake light switch at napa 10 bucks. Some wire, 18 gauge should be fine one male and 3 female spade connectors.

find the fuel injector relay under the dash to the left. It is a gray box as shown in the image. unplug the connector and then pull out the white wire holder in the back of the connector. A small flat head screwdriver applied to the ends where the white tabs show will free it. There is a black wire in the corner this is the ground, pull it out.

Run your length of wire, doubled, from where your switch will be to the relay. Two female spade connectors at the switch end.

Strip the insulation off one of the female spade connectors connect to one wire for the switch and place it in the connector where you pulled the black wire out, then replace the white wire holder.

Put the male spade connector on the other wire and plug it into the female connector on the black ground wire(s).

Secure your wires and attach the switch, all done.

Motor dies quickly you know it is dead when the red battery light comes on, restarts instantly with pop of clutch or turn of key. When you press the button the check engine light comes on then goes back off when you let go of the switch.


Learn from the mistakes of others, that way when you mess up you can do so in new and interesting ways.

One mile of road will take you one mile, one mile of runway can take you around the world.
