I just purchased a 2002 4Runner which has a viper alarm installed. While the viper horn is wonderful for piercing your eardrum from a mile away I prefer the most luxurious beep of the factor "buzzer". I tried to run a wire from the viper horn to the factory horn to see if it would work but had no luck. Any ideas how to wire this to work?

 

Does anyone have any suggestions? This horn is driving me insane

 

Press the aux button right before you press the unlock button, or vice versa when your locking it.
I was bored the other day at work and read the manual for my viper..

This may not help getting your factory horn to work with it but it will shut up the ear piercing chirp..

 

awesome, that will help for the time being
