I bought my cable from Johnstone, however I think the Johnstone
diagram has changed since I bought my cable as mine didn't come wired
that way (but close).    Even so, mine did not work wired-as-arrived
with my Highway 100 converter, plus I have a thing about avoiding
ground loops, so I redid it as follows:

IIgs            SCART
01 red gnd    -> 13 red ground
02 red video  -> 15 red video
05 grn video  -> 11 grn video
08 +12v       -> 16 RGB control via 270Ω
09 blu video  -> 07 blu video
12 Cmp video  -> 20 Cmp video
shield        NC shield (shield wire attached at SCART end only)

This list of connections is the total connections list -- not a list
of changes.  Note that I removed sound.

With this simplified cable, I've had no issues with any of my SCART
equipment... Samsung 910MP, Aptus SCART->YUV converter, and Highway
100 SCART->VGA converter.

Steven Hirsch ran into a similar issue when he received his Hwy 100
converter and SCART cable, so we made similar modifications to get him
going.
