Alarm wiring advice

[jce132]

I recently installed an alarm/keyless entry on my '90 GS, but can't find a wire that activates horn honk. The alarm is Bulldog Securities #1402, and the horn output is run through a 14v relay. Oh yeah, GRN/BLK and GRN/WHT don't work, I've already tried splicing into those. Any suggestions?

Have you tried whatever wires run to the horn fuse or relay?

im pretty sure in able to activate the horn you need a ground, you are trying to use a 12v source.. find the wire you think is needed for the horn, get a test light (grounded) and probe it, i bet it goes off..
