Here's a neat idea. With so many manufacturers recommending their parts are wired directly to the battery rather than another power source (such as the ignition switch), the positive stud on the starter motor can get rather crowded. So, Ron Francis developed this Multi-Connection Junction Stud, which is mounted near the starter. The supplied power cable connects to the positive starter stud, and all the accessories are wired to the Junction Stud. As it's mounted near the starter, care should be taken to install it where it won't get wet or struck by road debris.
