Yes, the white wire is ground. It is to provide ground for the LED. Black wire is 12 volt and the blue wire connects to the trailers brakes.
Yes, Bud I believe that you are correct on the white wire. I have never seen ground wire on the switch itself, but I guess that it could have one. My brakeaway switch only has the mounting tab and two black leads. On etailer I do see the battery pack for the brakes do have a black, blue, and white lead. I can see having a ground wire for that, but not the switch as it is only breaking a circuit. JMO
