In regards to the 7-Way Molded Trailer Wire Connector part # H20043, the yellow wire is for the reverse light circuit yes. This should then align with the pin responsible for the reverse light circuit on your vehicle. The terminology used for "AUX" is the same as the reverse light circuit. Please note, if you are rewiring a trailer I highly recommend you use a junction box, the Trailer Wiring Junction Box part # 3375601101 to keep everything organized.
We also have the Trailer Wiring 7-Way Upgrade Kit part # HS381-9000 which when paired with the Bonded 4 Wire part # 16-4B-1 (per foot) would come with pretty much all that you need.
