You can go to Powerlet and order the Standard Powerlet Socket (PSO-001 $15.95) and the Cigar adapter cable (PAC-002 $19.95), which will allow you to connect any US cigarette plug to your bike. The Standard Powerlet Socket has the same pin configuration and mounts the same as the Triumph power adapter.
