Happy to find this topic.
Just purchased 2014 Ford Focus and have run into many unanswered and conflicting statements from Ford and Dealer and this really clears the air for my install . The battery cable is one that no one can clearly answer. I also believe by the disconnect of positive all should be good. We are now in Rio Grand Valley of South Texas and will this next week make contacts for the install.
Plan on purchasing Blue Ox base plate and wiring that use seperate sockets and bulbs, just as you did, to avoid warranty problem.
One concern I have is that I have a Brake Buddy and with no power to plug into cig lighter will have to do something different. I think BB has supplement wiring.
Thanks for all of the above info.
Will keep posted on progress
Bob
