Wiring a 7 Blade Trailer Harness or Plug

Have you ever asked yourself what is the center connector on a 7 blade plug? The purpose of each blade will vary between the trailer and car end, they will both have a blade for tail/marker, charge, right turn, brake, ground and left turn. The center connector on a 7 blade plug is for auxiliary in case you want to keep the fridge going while on the road - it’s always nice to arrive to your destination knowing you have a cold drink waiting for you!

Here’s an illustration which may help guide you through the wiring process for a 7 blad trailer harness:
