Review on Hopkins 40495: The Ultimate Plug-In Simple Vehicle Wiring Kit Solution! by Greg Mcnealey

This product has been used less than 4 months and no longer works. The box was the problem. I only used it 3 times before it went bad. Bought a new trailer 4 hours from home, hooked it up and drove off and it had constant traffic lights with no brakes. I put the meter on the wires in front of the box and applied power. Put the meter on the other side and had constant power for everything else. So I cut out the box to start my journey home and everything worked fine.
