hey guys i have a 2003 toyota 4runner sr5 that i am installing a code alarm ca-5550sst. I have the wire diagram and all that and have the wire to hook up to to make the horn beep. My question is, on the factory alarm when locking and unlocking the car, the horn doesnt honk but there is a beep that the truck makes, like a electronic beep. Is there a way to use that same beep on my aftermarket system instead of having to use the horn? thanks for the help
Jon
