Default ATX power supply to bench supply conversion

Hello,

Not sure if this is the best group for this. I found several articles
on the process of using an ATX power supply and convert it to a bench
supply. The problem I am having is that the wire color codes and pin
outs are not standard ATX. I looked several places, including this
website, to see if I could find out what the pin outs would be.

It is a LiteOn 140W PSU with +/-5V, +/-12V, +18V, and +5V standby
(underside of the PSU). I actually had to open it to see what wires
were what voltage. The board actually has them listed as:

6 Red: +5V
5 Black: Ground
1 White: +18V
1 Yellow: -12V
1 Purple: -5V
1 Grey: PG, I am guessing 'Power Good'
1 Orange: +12V
2 Brown: P/C and F/C (not sure what these are supposed to be)

The pinouts from 1 to 20 a
