Does anyone know where I can get these light assembly parts without being taken by the Stealership?

 

take them to any auto parts store, a wall display will have all types of connectors
Ask for help

 

Or visit your local parts yard

 

Advanced Auto Parts and NAPA didn't have anything for Acura or Honda.

 

Those parts are DEALER ONLY no aftermarket does them.
So unless you wanna go OEM check your local junkyards, Honda uses those like candy in most of their cars so don't stick with TLs only.. Accords, Civics, Etc. Will use them.
