Step 1.
Remove the mirror.
Pull off the wiring harness from the back of the mirror, there’s one tap to press while you pull. Pull off the plastic cover at the mirror base where it attaches to the windshield. Use the T15 screwdriver to loosen the mount screw, you don’t need to loosen it much for the mirror to come off.


Step 2.

Opening up the mirror
Put down a towel so it doesn’t get scratched up and lay it mirror side down. Use the trim tool to pry at the edge in a spot that isn’t visible when the mirror is installed, like the top just in case you scratch the plastic. Once you get a section up just keep going around and prying until the entire thing comes off.


Step 3.

Changing the color of the status light.
Pull the board out and disconnect the harness from the board. Look for the LED, it’s laid on the board facing inward in a slot. Note the polarity direction of the LED and just heat up the led where it attaches to the board and slide it off. Install the new one the same way just lay it in and heat up the connectors until it’s attached. Place one gray adhesive overlay on top of the led where it faces. This will reduce the brightness a bit which I found necessary because it was way too bright without it.


Step 3.

The Map/Temp light

Use a razor blade to cut underneath the dark blue overlay thing on top of the display. Once it’s off cut the new adhesive in the same shape. I did two blue strips followed by a single gray strip to darken it so you couldn’t see the blue overlay during the day. With that done you’re almost done.


Step 4.

Reassemble
Lay the board back into the housing, reattach the small harness. Get everything lined up and then press the trim section back on. With that together take it back to the truck and reinstall.
