They sell a tool (sold separately) of course. I haven't put one on yet, but assume that once I see the tool and Bendix I will be able to figure it out. I don't think you have to have the tool, but they offer it and so I put it in stock. I've had one club member use the new style and had trouble with it in just a short time. I think I will stick with the standard Bendix. The truck cam with 12 volt and I've already had to put a Bendix on it and haven't had any trouble with the stock Bendix since. Just my thoughts
