I installed Murph's wiring harness in 2010. I did find hard copy instructions in my files. mgoodrich says he has the diagram in .pdf and will send it.
The applicable section reads:
"Holding the OEM headlight socket with the terminals at 3,6,and 9 o'clock, insert the white wire on the left, the plain black wire on the bottom, and the black wire with the red heat-shrink on the right."
Left = 9 o'clock, Bottom= 6 o'clock, Right = 3 o'clock.
On the last page of the instructions is an "Addendum for Reserve Lighting Device equipped Concours". It says that early models came equipped with a Reserve Lighting Device. It instructs how to remove this device from the bike and install a jumper on the remaining 9-pin connector. The jumper is between the blue wire pin and the blue with yellow stripe pin on the female half of the connector. The device is mounted to the fairing stay on the left side, under the left hand fairing pocket. I did not pay attention to this Addendum as mine is a '06.
Good luck. Let us know if you need more info.
