Two options. Sorry not having gone there yet I don't recognize the part directly.
One: get yourself the factory DVD or "rep-rom" as it's called, and become familiar with it. An official copy costs about $100, bootleg much less.
Two: go online to the parts fiche at realoem.com and enter your VIN number, then drill down to the assembly in question. This one's free; the parts diagrams are available also at the websites of most major dealers, but realoem was the first (IIRC) and has been my go-to for many years.
Both methods are useful, the second a little quicker and will impart peripheral knowledge which may be useful.
