So, the technicians ask me "what is that plug for"? "What is that big box for"?
Me, how the hell should I know...Do I look like I'm a trainer...Crap, that is what I'm supposed to do..
So, what do I tell everyone:
"The plug is for the lowside switching accessory package and the black box is part of the EVAP system, don't touch either of them".
Damn, I'm good.
