What Style of 7-Way Plug Does the Electric Jack w/ Footplate and 7-Way Plug Use

Updated 05/04/2024 | Published 03/27/2023

Question:

Is there information on which of the 7 way pins is actually providing the power to the Jack. Id like to install a female plug on my trailer and use the house batteries to run the jack. So, I would need to know what pin is Positive, which negative, and ground. Thanks.

The Electric Jack w/ Footplate and 7-Way Plug # EJ-3527-BBX uses a 7-way RV-style plug. I have included a diagram that shows the pin-out for RV style 7-way plugs. This will show you what each pin does. I have also listed the functions below and linked to a help article that covers this.

Green: Tail/running lights
Yellow: Reverse Lights
Brown: Right turn/brake light
White: Ground wire
Blue: Brake controller output
Black: Battery hot lead
Red: Left turn/brake light

(Facepalm) forgot to unplug the 7-pin from tow vehicle…. Need to repair the plug: Which wire is hot and which is ground? Wires on unit are black and red. Thanks!

Saw that the red has the fuse, so expect that is the hot vs the black…
