you need to be CAREFUL!!!!!!!!!! the wire is in the airbag harness.see the note below.

OEM Horn LT.BLUE/RED (-) AIRBAG HARNESS

I would try to find it a little further down the line so that you stay away from the airbag harness. what is the out put from the alarm?? can u program the output to pulse?? otherwise the horn will blow non-stop when you trigger the alarm. if you are using the siren output and its 12v, here is the relay info....

87 and 86 go to ground
30 goes to the horn wire
85 is 12v from alarm siren wire

make sure you have a fuse on the 12v wire.

good luck,
david
