Where do you attach the snapper arm to a mousetrap car?
The snapper arm, is the long thin stick thing, right? Ok then. You attach that snapper arm, to the little semi-curved rectangle, the small one. So when you pull the snapper arm across the mousetrap, it hits it. You just slide it in there, with the more hook part facing up. But you have to kind release the bar you pulled down, just slightly so that the snapper arm will stay in place.
