How to Wire a US 7 Way to a Australian 7-Pin Flat

Updated 05/15/2024 | Published 05/13/2024

Question:

Please help in converting a US 7 blade rv trailer plug to a Australian 7 flat pin plug. I bought a CURT 56357 Vehicle-Side Custom RV Blade 7-blade Trailer Wiring Harness. However, i live in Australia which has a different 7 pin plug. It seems that the Aus plug has a dedicated stop light wiring while in the US plug, stop is integrated to both the left hand and right hand signal. Im planning to cut the wires and place it to an aus 7 flat pin plug but need help with mapping the right wires. Thanks i attached pictures of both 7 blade and 7 pins for reference. Ta.

Hey Kent, so to wire up your 7 way you're going to need to remove your 7-way round on your vehicle and wire it to match the Australian 7 way and use a converter # 118158 to separate the turn and brakes.
