The horn on my 2000 CIVIC SI is not working, and I try to find the horn wire, but can't seen to find it, anybody have a wire diagram for a 2000 civic si?

 

Horn GRAY (-) STEERING COLUMN OR GRN PLUG BEHIND RADIO

to test if the horn is still working, splice into the horn wire, connect a wire to it and the end of that wire to ground. If the horn is still good, it should still honk. if not then horn or relay is gone.

 

so behind the radio is the green plug and which wire is the horn wire? So what you saying is that connect a wire on the green horn wire to ground? Also, where is the relay located at?

 

There is a green hardness on the left next to the radio on a 2000 CIVIC SI, anybody know what that hardness connected to?

 

uhhh....its actaully a GRAY wire. Its located at the steering collum and behind the radio. I suggest you go to the steering collumn since its easier to get to.

 

Solve the problem! It's the horn that is not working. Thanks for your help....Also, I have a green hardness on the right side of the steering wheel, you know what that green hardness connect to on a 2000 CIVIC SI?
