dimmer vs illumination wire/ 08 Honda Ridgeline

In this video, I briefly give a description of what the illumination and dimmer wires are for...and what to hook up (in my application...and most that I've come across.) The installation involves a Hikity (NOT SPONSORED) touch screen stereo with their harness, and an aftermarket wire harness (Harmony audio...NOT SPONSORED) and how and what wires I specifically spliced together and which I didn't;-)
