Well bello, I believe I figure it out.

I'm now working from your updated pic.

Your going to add a small length of wire to the LEDS to connect 2 others too.
Orange wire connects to positive side of P2 plug. Negative to connect to the LED's. LED's then connect to the power source(there should be a Y connection now) (+12v line). While the last terminal in the tip31 connects to the ground wire on the molex. On the same cable as the ground wire connect the switch. So another Y connection.

Molex power set up
Yellow,Black, Black,Red
+12v, -12v,Ground,+5v

Make any sense?
Photo of what I'm meaning is coming soon, as the above could be confusing.
Please be cautious when doing this as I "believe" this is how its done.

As for your question about the molex connector.
http://www.google.com/imgres?imgurl=http://www.logicsupply.com/images/photos/cables/pwry-3m_big.jpg&imgrefurl=http://www.logicsupply.com/products/pwry_3m&usg=__WnlY2P3fPrEL69w3PKiiv_D4mtk=&h=400&w=600&sz=45&hl=en&start=28&zoom=1&tbnid=jCUIMKHVMYEVQM:&tbnh=151&tbnw=196&ei=L91DTZCiGYmmvgOg1t24AQ&prev=/images%3Fq%3Dmolex%2Bconnector%26um%3D1%26hl%3Den%26biw%3D1680%26bih%3D802%26tbs%3Disch:10%2C684&um=1&itbs=1&iact=hc&vpx=1195&vpy=126&dur=3535&hovh=183&hovw=275&tx=117&ty=115&oei=JN1DTYqEJozRcNacjeUN&esq=2&page=2&ndsp=32&ved=1t:429,r:6,s:28&biw=1680&bih=802

You will need the connectors on the right to plug into your system, you can buy them from local computer shops. You will notice that the ones on the left are similar to what you already have in your pc.

The attached image shows what I was meaning by the Y connections previously.
Green lines, you need to add/fix
Black lines, you need to remove.

This should now power the leds for you.

Thanks for the multiple PM's. We figured it out in the end. The pics below are for the community.

What was PM'ed to me.

What needed to be fixed
untitled-1.jpg

The result a working, "blinking" led light set that flashes to the beat of music. Waiting for Bello to post the final result.

Great idea major draw back..

You must use a jack to get it to blink. I been trying to find a way to do with with out doing this. The only solutions i have came up with are USB headphones / Switch to switch between head phone jacks and rear.
What i hate the most is that this seemingly cheap project racks up in cost if you want to do it right.

TIP31 $2.50
Proper LEDS $5.65
Rocker Switch $2.95
Housing Box $5.75
Proper 3.5mm Jack ~$3 X2 = ~$6
Molex Connector + Pins $6.96
PCB Board $2.89

Before you know it your little light show just cost you $32.70

There are projects online that user a timer to determine how fast a group of led's will flash. Type "Blinking LED 555" into Google and there is a lot of links on how to do this. Which would work out a lot cheaper than what you are describing StuffStuff1.

I should have been more specific. Blinking with Music.

Just use LEDs that require less power. or start playing around with resistors. Series vs Parallel.
