I was looking things over prior to beginning the install and realized just how low the plug will hang below the bumper. Here's the wiring diagrams showing the pin out for the plug and socket for the most common circle and rectangle trailer connections in use in Australia. There is a trailer pig tail behind the passenger side rear tire.

I performed a few searches and found pictures of different mounting points, such as in the bumper, but was not able to find any kind of.

I put this here because I had a hard time finding and figuring this out for my trailers.

Trailer wiring can be difficult to get your head around. Go to a hardware store and select an adapter that joins the two different types of wiring harnesses. When I check for running lights, L&R turn/brake signals, everything checks out.
