Ok guy's I need your help. how do i wire up my alarm for it to honk both the horn
and the siren?My alarm has an output for both of them. The output for the horn
is negative, i have tried wiring the horn using relay's,direct wiring and none of these
methods work. I'am not a newbie at installing car alarms but this just leaves me
puzzled I know that the horn wire is located in the steering
column and that it's a (-)negative orange wire, but why do 3 orange wire's just become 1???

here's a link to my alarm's wiring diagram.

It's pg.27 of 27


Any help is greatly appreciated.

all i can say is make sure you have the right wire and make sure its ground. i couldve sworn it was positive, otherwise you might have just blown a fuse...double check and make sure your horn is still working..i dont see why a relay wouldnt work. test for your wire and then hold it to ground and see if you can make it honk that way..

Horn wire is (-) orange, so it should connect directly w/o a relay...

I did connect it directly but the horn still wont sound.

Maybe there is a switch or a setting on the alarm brain that needs adjusting?

It is probably where you are connecting to the horn signal. Measure the voltage of the wire you are connecting to with the ignition on. It should be 12V.
