Bummer...
All I can suggest is to look very close at the board contact area for each of the wires; use a magnifier. I do not remember if it is on the side your picture shows or the other side.
Each of the connections for the 12 wires on the board would have had a copper/or other metal strip that the non-existing plug contacts would connect to. Peeling the strip back exposes the name. Do you see any writing where the wires are connected to the board or on the back side of the little tab?
If anyone on the board has a cluster out...please snap a closeup picture for Hitman. Or if you remember the post...post a link, I searched but did not find it either...maybe rennlist?
Thanks,
Jon
