Ok bear with me, Mr Triumph likes playing games here is the correct wiring if using a 7 pin flat Aussie plug, I will keep it as simple as possible
Trailer plug................................................................ Triumph
pin #& funtion........ trailerwire colour........... wire colour on main harness side of plug
1 LH indicator............. Yellow............................. Green with Red stripe
2 not used**............. (Black)
3 Earth .........................White.............................. black (I used plate light plug)
4 RH indicator ................Green............................. Green with White Stripe
5 not used ***........... (Blue)
6 Brake Light................. Red .....................................Blue
7 Tail Light.................... Brown.......................... Yellow if taken from plate Light Plug
..........................................................................or Red if taken from Tail light Plug
** only used if you are fitting reversing lights (no we dont ride Glodwings)
*** only used if you want to use Electric brakes or Auxilery power in trailer
I Hope this helps, not sure exactly if plugs will be in the same place on a Touring but on a Std or Classic they are adjacent to ECU just tucked in behind metal tongue, under right hand side cover
