R/B was connected to B/R heading to the rear loom?
Could be cig lighter?
According to the diagram I was looking at.
This DOES connect to the inspection light.

Last for now.
Rear passenger, not connected.
From a @Coolerman post, I think the B/R is backup.

Ohmmeter is your friend...
 
It's time to educate yourself on the reading of the wiring diagram. You might print a few off and use highlighters to trace each circuit. I will vouch for the multimeter, I couldn't do my job without one!
 
Good luck , It"s not going 2 be easy , It"s usually 2 steps forward and one step back for me , And still not right ,
Plug in the connectors that are the same male ,female first , and trial and error the rest ????
