I've got a 2008 quad cab with factory installed remote starter and the horn blows when I start it with the key fob. Is there a way to disable the horn from blowing?
I'm sure someone else has posted this problem before, but I couldn't find it.
Any help would be appeciated.

 

Dealer can do it with the starscan

 

or disconnect / cut the wire that goes to the horn relay

 

Not a fan of waking the neighbors in the morning? Both Severe and gish got the right idea
