im currently installing an alarm in my 93 civic dx 4dr, but cant find two wires. i need to find a wire that connects to the dome light and one that goes to the horn. thanks for any help.

 

^ noone?

 

The door trigger wire (dome light) is green with a red tracer, it is in the driver's kick panel and will read 12v with the doors closed and 0 volts with a door open.

The horn trigger is blue with a green tracer and can be found with a group of wires coming from the steering column. It also will read 12v normally and go to 0 volts when the horn button is pushed.

 

The door trigger will only show 12 volts with the door closed if the bulb is working and if it is set in the door position.

For your year, there is like 3-4 wires of the same color, only one of them will do ALL doors, so check and double check. Most will do the drivers door only.
