Does Hot Lead Have to be Run to Vehicle Battery

Question:

Hello, Would it be possible to run the module hot lead on an external 12V 7A Battery like the ones used in UPS systems? I was thinking of doing that instead of running the hot lead all around the car to the front main battery Thanks

You can only run a hot lead to the vehicle battery when installing a trailer wiring harness like the Hopkins Plug-In Simple Vehicle Wiring Harness with 4-Pole Flat Trailer Connector # HM11143894 on a 2011 Subaru Impreza Wagon.

You need to run a hot lead to the battery because this is the only way to ensure your car's wiring is not otherwise affected. To do this you may need Wire Loom, 10' Long # 7509-10 and Loom Clamp -1/4" # A0250. I have added a link to a help article on routing a power wire to your battery for you to check out.
