Overview
I had the original 4 pin trailer wiring harness installed by Subaru when I purchased the vehicle. However, I would like the ability to connect up my camper without having to use a 4 pin to 7 pin adaptor. In the future, I would also like to be able to charge my camper battery while driving.

Wiring
For Now
For now, I simply connected the 7 pin harness adaptor to the existing 4 pin connector and zip tied them together. I screwed the white ground wire into the body of the car. Later I will connect up the black wire (12v power) to the battery using the relay and circuit breaker listed in the parts section.
