kyomagi:
ok last two questions i think.

On these leds, http://www.paradisearcadeshop.com/en/led-pushbuttons/231-green-led-convex-arcade-pushbutton.html, does it matter which is ground and which is power?

And should i just snake the cables together, then strip the yellow and black wires at one end, then connect?

If you're placing an order with Bryan, he has 1/4" daisy chains.

30 Connection Black Daisy Chain (.250") - Makes wiring the LED buttons really easy http://www.paradisearcadeshop.com/en/jamma-harnesses/406-30-connection-black-daisy-chain-110.html

30 Connection Red Daisy Chain (.250") - http://www.paradisearcadeshop.com/en/jamma-harnesses/407-30-connection-black-daisy-chain-110.html

If the wiring is backward, just unplug and reverse the LED holder (red cylinder between the black socket and red button) -- no damage done.

If you have a power extender/splitter/adapter cable, you can avoid cutting into the PSU wiring.

I am buying a molex cable and i will cut into that.  In fact, i have a bunch of spare pc fans that have molex connectors.  i'll just cut those
kyomagi:
So i am changing the buttons on the wwe brawlstick from madcatz.  I am modding the graphic too.  But these buttons are too big with the microswitch, and when i add the daisy chain i made, its about .5" too big and it wont fit.  is there anything i can do? maybe some washers for space between the base and top?

rather than using the quick disconnects, can i just solder the led daisy chain?

 :dizzy:  Now I'm confused.  :dizzy:

First you wanted to light 16 buttons.

Now you're changing buttons on a Madcatz Brawlstick. (8 button stick.)

To answer your specific questions:

1. Soldering the daisy chain - I'd strongly recommend against it. .250" QDs are cheap and widely available. If you decide/need to change something later, desoldering/resoldering is a real pain.

2. Buttons are .5" too big. - From the context, I assume too long? Consider using something like these .250" "flag" QDs.  You can probably find them locally at auto supply stores, hardware stores, walmart , etc.
If Bryan's buttons fit without the LEDs being wired, the flags should allow you to daisy chain with almost no additional height added.  Also, washers/spacers will make the buttons stand way too high.
