Converting Neo 480 PSU to 2nd AT PSU?

I have a Neo 480 PSU that I want to use as a secondary PSU. Of course, since I cannot connect a second PSU to my motherboard I cannot use it. In the new issue of Maximum PC they briefly discuss how to convert an ATX PSU to an AT PSU by "shorting" the main power connector. This involves putting pins into two spaces on a 20 pin main power connector and building a switch to turn the PSU on or off. Since the Neo has a 24 pin to 20 pin adapter, I assume I could use this trick, but I have some questions.

(1) Where can I buy pins?
(2) Do I need to build a switch, or could I just the on/off switch on the back of the Neo?
(3) If I use the 24-20 pin adapter, will this trick still work?

Thanks for any help.

If you use an adapter, it is very easy. You have to cut the pins on the adapter, and solder a switch to these pins, so that when the switch is "on", it shorts pins 5 and 6 (I believe, look at the picture in Max PC). The beauty of doing it like this, is that when you no longer need to do this, you can remove the adapter, and throw it away, and your power supply is perfectly fine. I wish I would have thought of that, as I just cut the cables going to the 24p block. Oh well though. It still works like that too.
