My friend had his alarm on his 99 si hooked up to his horn so that when he honked the horn it made siren noises instead of the traditional horn sound. I wanted to know how to do this , i dont care if my alarm doesnt work i just want to hook it up to my horn. what wires need to be cut, crossed, connected and where are they? any help would be appreciated. I know this can be done b/c my friend had it on his civic. I tried the search but there are no posts answering my question so i made my own.

all you gotta do is disconnect the wiring harness from your stock horn and connect it to the siren. Just make sure that you have the positive and negative connected right.

 

could u tell me if any wires need to be saudered together, and where i might find the wiring harness. i just need basic directions so i dont mess anything up. Thanx

just take the wires of your stock horn and re-route them to your siren. just make sure you have the positive and negative correct. you dont have to solder, you can probably splice the wire or you can cut it and add new wire to it with butt connectors and then connect it to your siren and use another set of butt connectors and then voila your horn is a siren.
