So I want to scrub/clean/power wash out my rear body/floor in my trunk. & where I think the drian plug is in the center of the floor but I couldn't really see if it came out the other end. As I was pulling on it, it started breaking off, so I didn't want to try anymore, just in case it was something I shoudn't be pulling on. Soooooo if anyone could tell me where it is exactly or even better shoot a photo of what I should be looking at. THANKS!
