Electrohome G05-802 deflection board revision question

I have a deflection board for an Electrohome G05-802 monitor - the board
part number matches the number listed in the manual - however, the board
revision is "issue 2" and the revision listed in the manual is "issue 5".

P500 on the schematic lists the "key" at position 5, while the board I have
has the key at position 4.

The foil diagram for issue 5 matches the actual layout for issue 2, except
for pins 4 and 5.

On issue 2, pins 4 and 5 are electrically connected, but the wire that
connects to pin 4 is purple, and it runs to the CRT neck socket where it
terminates since there is no CRT pin that make connection to it.

Basically, the situation is that I have an "issue 2" deflection board for a
monitor that seems to want an "issue 5" board. The immediate difference
between the two (other than the obvious key change) seems to only affect a
connection to the CRT that is electrically isolated.

If I just "move" the key from pin 5 to pin 4 on P500 on the deflection
board to allow the board to be used, are there any other potential issues
such as components in the "issue 2" board that are not compatible with this
monitor?

Does anyone seem to recall electrical differences between issue 2 and issue
5 deflection boards?

Just wanted to get some second opinions before I plug this sucker in.

I would appreciate any insight that members of this group have. Everything
that I see on the revision 2 board seems to match on the schematic for
issue 5, at least as far as I can see. But we all know that it's the little
things that'll get ya.....
