Difference Between 7-Way Wiring Diagram that Uses Red Wire and Purple Wire
Updated 08/11/2020 | Published 08/07/2018
Question:
The 7-way trailer connector on my trailer was damaged by accidentally falling out and dragging on the ground. I am replacing it with a new connector plug . I am following the right-hand diagram I found on your website: https://www.etrailer.com/question-363.html All of the wire colors in my trailer cable match except that there is no purple. There is a red however. I connected the red to the center terminal where the purple would go. Is this going to work? Or am I going to short out some of the wiring? I was unable to gain access to the back of the old connector as it was molded around the wires.

Expert Reply:
There are actually two ways that 7-way wiring colors are commonly seen. One uses a red wire and the other a purple. The circuits they represent do vary though. So check out the updated diagram I attached to this page and most likely you need to wire the connector up like the center one.
