After drilling the holes, we're going to slip in the LED bezels in place. They should slip right in if you made your holes correctly.
Next, unscrew the top nut on each switch. You're going to need this to secure the switches to your faceplate.
For demonstration purposes, I am going to hook up a few of my Panaflo bare wired fans to the the bay bus. Red goes in the red screw down and black in the black. Get a small flat headed screw driver, it will definitely help you out in tightening the screws.
Here is the final result. You may have to give the LED bezels a little force to get them all the way onto the LEDs. A little tight so push very gently. Also, hand tighten the screws. You don't want to over tighted it and break the darn thing.
Here is the bay bus in our test case with the outer two switches running full speed and middle two at about 7V. We ran it for about a full day to see if the bay bus would get warm or hot, nothing of that sort was apparent. The device ran rather cool I might add.
Overall, the device is excellent. The complete kits comes with all the parts you need. There is also an instruction sheet which we didn't even bother to follow (oops). The item does what it's supposed to do, quiet a case down when you need it.
Thanks to UmaxPC for sending us this test unit, at only about $19 this is a steal in my book.
