Thanks for the replies. I have now also located the plug.
The information on the plug is in the 2003 EX manual on page 240.
In case your manual does not include it, a poor description is as follows:
From left to right in the shape of a U:
Ground (black)
Right turn signal (green/yellow)
Back-up light (green/black)
Brake light (white/black)
Taillight (red/black)
Left turn (green/blue)
Thanks, David
