Trailer brake light wire is the white-red wire under battery cover. It comes directly from brake pedal switch but Alfa did not put in a connection for tail lights or turn signals.
I doubt if Hoppy or anybody else makes a adapter kit for Alfa to wire up a trailer for tail lights and turn signals so you will have to make your own.
