Review on 🔋 WirthCo 30110 Battery Doctor Placement by Mike Travers

I thought this would work as a fuse box with a side power supply and all output leads, fuses protected. To do this, you need to combine all the pluses together. I don't see why you would actually need a fuse box to which you would probably need to connect the four positive wires from the battery if you don't connect the terminals. Maybe I'm missing something. Perhaps they should include a jumper in the package or suggest a jumper that can be easily plugged in.
