I upgraded my unit and had to deal with this. the #8 part is antenna for keyless entry, to determin your fob is inside the vehicle. #1 is a white LED strip that sits in front of the cup holders, mostly as a highlight accent in the dark, as it's not overly bright. I bought a used upgraded unit from a handicap van upgrader, and neither of the pieces were included, nor was the harness, I was able to use the antenna from my lower trim level console, and purchased the LED part and harness from one of the online parts dealers.
