Horn honk wire at the keyless entry module

[Turboweasel]

Hi guys, do anyone know if there is a wire at the keyless entry module that honks the horn for the second press on the lock button on the fob?
I would like to use that as a trigger wire to activate my coming home/leaving home module. It turns the headlights on when I lock the truck, but that way it will only activate on the second press.
