No, sorry we do not know the orientation of the factory wiring as far as functions go. You would need to use a circuit tester like the item # PTW2993 to identify them. The Hopkins Plug-In Simple Vehicle Wiring Harness item # HM11140825 that fits your 2013 Infiniti G37 Coupe is a plug and play set up though. You do not need to splice into your Infiniti's wiring. This has custom fit connectors that plug in your rear cargo area on the driver's side and passenger's side.

To install the item # HM11140825, you will have to remove the rear threshold and some interior lining to access this harness. Once you've plugged in the connector, run the red hot lead up to your car battery. Then you will connect the included fuse holder, and finally connect the fuse holder to the positive terminal on your battery.

Additionally, the Curt item # C56033, you were looking at, does not fit the coupe model of your Infiniti. Only the sedan model.
