Ok so I was bored but still dont want pop the sticker off of the 360, not to mention I'm waiting for a couple Iwatas to come in before I start on it.
So I though I would have some LEDs in my Intercooler.
I used this TUT for info on where the 5v/12v and ground wires were.
http://forums.xbox-scene.com/index.php?showtopic=5163981st thing take the IC (Intercooler) and take out the 3 screws. That piece comes right off.
Under that is another piece which has 2 screws and in my case the screws were VERY tight. Be carefull not to strip the heads.
Determine which unit you want to pull power from. (I used the one the actuall PSU plugs into)
Carefully dig out all the hotglue.
This is where we are at now.

Now we need to build our string of LEDs. I decided to use 2 strings of 5 with 1 resistor per string.
So for each strand we need 1 pos wire and 1 ground wire. I cut small sections since this is my "hot" wire
and I don't want the chance of shorting it out on something.

Longer LED legs are POS, attach them to your POS wire.

For my neg wire I striped most of the shielding off since it is simply a ground and I knew I could hotglue any possible spots it could come in contact with a "hot" wire.
So now you sould have all your LEDs attacked to a POS and ground wire.
Easy huh.
Here is an image of th power sources in the IC labeled.

I used the 12 V in my application
Gently pull the wire out of the socket it will not come out all the way.
When you get it to where you can see some of the metal piece attached to the wire get some needlenose and grab the metal piece and pull the wire out.
I soldered my strands directly on the metal piece but close to the wire to not interfere with reinserting the wire into the socket.
I am not sure if it makes a difference but I used a seperate 12v source for each strand. I assume it better to spread the load than pile it on one socket possibly overheating that socket.
I then wound the 2 ground wires from my 2 strands together, removed a ground wire and soldered it on. If you do it right the wire will plug right back in its socket. My case I diddn't have the wire perfectly aligned so I had to trim a little plastic out of the socket to make it work.

I then filled that unit with hot glue to hold everything in place like it was before I took it apart.
This is where we are at now.

IMPORTANT: I found out the hard way. There are 2 small holes in the unit and the glue will seep through the otherside making it impossible to plug in the PSU into the IC. I just dug it out very carefully on that side. I imagine if you stick something in the holes it could prevent that.
Anyways
Postion your LEDs to get the most light but disrupt the airflow as little as possible and hotglue in place.

Reassemble, it will take some work to move the wires around to get everything back together without crushing everything.
Sit back and enjoy the fruits of your labor. smile.gif

Again I want to give credit to Morlok8k for using his photo of the power sources on the Nyko Intercooler.
