*NOTE*
The AS-2518-23 Lamp Driver Module does not use the CD4050 hex driver chips
so ignore that column if that's the style of lamp driver you have.
This table lists all the MCR-106 SCRs on the Auxiliary Lamp Driver (AS-2518-52),
the name of the lamp it drives,
the MC14028 BCD/Decimal decoder IC associated with it, along with the BINARY input signals (ABC) and the output pin,
and the 2K Ohm resistor (red/black/red) connected to the decoder output.

*NOTE*
I really don't know what this means and I can't find any explaination on the schematic either.
I'm guessing they really mean the solenoid expander board since I didn't find a connection to in
on the lamp driver, but pin 3 on it is ground, so I don't know.
NOTES
I got all this information from the schematics and pretty much copied it verbatim.
If you notice any mistakes (I'm only human), please let me know and I'll fix it up.
