To install a replacement jog wheel, the first step is to connect the left jog wheel (viewed as right on the controller) into the empty slot.

Next, align the screw holes on the jog wheel unit with the holes of the jog wheel frame.

Now that the holes are aligned, you are going to need 4 black screws. Using a philips head screwdriver, screw the 4 black screws into the jog wheel unit.

After that is done, place the polygon-shaped reader back on to the unit, and screw in the other 4 black screws using the philips-head screwdriver.

Then gently plug in the red, white, and blue wire bundle, along with the red bundle into their respective spot on the motherboard.

Repeat for right (viewed as left on the controller) jog wheel.
