Where to pick up SYNC from for a RGB mod.

[SuperPlay]

Quick Query relating to where to pick up the sync from for an RGB mod on a Core Grafx.  I have generally taken the sync from pin C22 on the expansion bus as per the mmonkey mod

However I have just noticed that the sodipeng mod seems to take its sync from: A22

Hwbook has "C22 as Sync Video" and "A22 as Vid"

Can someone please clarify :-)
