Question:

Howdy. Is the yellow wire pre-wired to the center post backup light of the connector? Thanks

For the Hopkins 7-Way Molded Trailer Wire Connector, 8' Long # H20046 the functions are prewired for you and color coded in the following way (which is a little confusing):

White Wire is your Ground (traditional White Wire)
Red Wire is your Left Turn and Brake (traditional Yellow Wire)
Brown Wire is your Right Turn and Brake (traditional Green Wire)
Green Wire is your Tail Lights (traditional Brown Wire)
Blue Wire is Brake Power (traditional Blue Wire)
Black Wire is 12 volt hot lead (traditional Black Wire)
Yellow Wire is Aux. (traditional purple wire most of the time used for reverse light function).

I've attached a video to help.
