Does anybody know what pin is what in the high voltage port for the external battery. I tried to look for a service manual but could not find one online.

Seems like it is a big secret ... I guess Canon doesn't want people to be DIY'ing 300 Volte power supplies.

That matches what I found! I actually want to use the battery pack on another project but thought it would be easier to find the pins on the flash than it would be on the battery pack.

That does not show you what you are looking for?

The HV Output is on the single pin opposite the key in the connecter, ground is the center pin, and the control is on the pin furtherest from the connector key.

Pinout for one must match the other.
