The chip i bought just barely fit and the Billy said it was a bit underwhelming for the work put into it. Leave it to movie magic and our imaginations..
the way to do it is to run the real airhorns in the bags, run a wire that is activates it, from the button on the box.
I like the plugs Billy, btw a non yoder but very similar horn ended a few days ago, it was nos with the box. Same mount and all.
I was probably going to cap mine too.
