Installation
Open up your DMG. Remove the power LED with a soldering iron, you can add more solder and then gently remove the LED.

Gently push the included light pipe into place from the bottom side.

Solder the 3 points of the flex board as shown.

Place the DMG’s front PCB back into place and gently move the flex into the spot where the original LED was. You’ll need to tape it down to secure it in place. Be very careful when moving things around as there isn’t much slack on the flex board and it can be damaged.

We recommend placing some black tape so the LED doesn’t illuminate the side.
