You cannot directly attach the negative terminal to the battery, or the battery management system will not see that the battery is being charged. Please watch this video, at the minute 13 mark.
Thanks! I just completed installing the knockoff ARB compressor on the American Adventure Lab blank plate. Ziptied (with metal zip ties available at Harbor Freight, a very good thing) the Northern Tool hose reel (available on Amazon) inside the spare tire carrier. I drilled holes in the plate...
My wife just bought a bronco with ADD Baja style bumper in the front with no winch mount. We have 2 dirtbikes, and cannot cantilever both of them off the back. Desperately need a solution for a front hitch mount for a motorcycle rack. Retired Engineer and happy to help develop!

Great idea! Just got our Bronco and was trying to find a purpose for the tailgate hole, and also a compressor solution - perfect. Thanks for providing links to the products, you originally said the hose reel was Harbor Freight so I was unsuccessful in finding it of course.
Love that you have...
