What are the pin functions on a 7-way RV blade trailer connector?

According to the diagram, the 7-way RV blade connector pins are: Back Up, Auxiliary, Tail/Marker, Left Turn, Ground, Brake, and Right Turn.

What functions are on a 6-wire round trailer connector?

The 6-wire round connector includes Ground, Tail/Marker, Left Turn, Right Turn, and two pins that are either Auxiliary/Brake or Brake/Auxiliary depending on the wiring standard used.

Why does the 6-wire round diagram warn about Brake and Auxiliary pins?

The document notes that Brake and Auxiliary Power have two different industry standards, so you must identify which way your trailer is wired before wiring the connectors.

Does this diagram show both the plug and socket views?

Yes. For both the 6-wire round and 7-way RV blade connectors, the diagram shows face views of both the plug and the mating socket with each terminal labeled.

This document is a trailer connector wiring reference showing pin/terminal function assignments for two common trailer connector types. The left half covers the 6-wire round connector, illustrating both the plug (trailer side) and socket (vehicle side) face views with labeled terminals: Ground, Tail/Marker, Left Turn, Right Turn, and two terminals labeled Auxiliary/Brake and Brake/Auxiliary. A prominent note warns that Brake and Auxiliary Power have two different industry standards, so the installer must identify which way the trailer is wired before wiring the connectors. The right half covers the 7-way RV blade connector, again showing both the plug and the covered socket, with labeled terminals for Back Up, Auxiliary, Tail/Marker, Left Turn, Ground, Brake, and Right Turn. Each terminal label is connected by a color-coded leader line to its physical position on the connector face, allowing a reader to correctly match trailer wiring functions to connector pins when installing or repairing trailer wiring harnesses. No wire color codes, part numbers, vehicle years, or model applicability are stated; the diagram is a generic industry reference applicable to towing setups using these connector styles.
