Being new to both M249 and HPA setups, I chose a difficult project for my first. As far as I can tell Wolverine provides no manuals or videos in how to set all of this up. Thankfully Airsoft Junkiez to the rescue. The helpful video showed me that I just had to wire a JST connector directly to the motor on my MAG box magazine. After that it all worked together flawlessly. I especially like that I am given a variety of battery connector choices as some batteries are easier to find then others. Definitely recommend this to anyone running a wolverine FCU.
