Replacement 7-Way Trailer Connector that Uses Traditional Wire Coloring
Updated 05/02/2020 | Published 04/30/2020 >
Question:
Do you have a molded trailer electrical cable the uses standard wiring colors? The two I have gotten from you only add to the time it takes to replace as the wire colors mean nothing. Good quality but pain in the ass.

I looked up one of your previous order (Thank you, by the way. We love return customers) and what you've gotten in the past are 7-way connectors that use traditional RV wiring. The easiest way to pick them out is that they have a red wire.
I assume you're probably wiring a cargo trailer or maybe a car hauler. The only 7-way we have that uses the standard coloring is part # HM20041. The coloring is:
White: ground wire
Yellow: left turn/brake light
Green: right turn/brake light
Brown: tail lights
Purple: reverse lights
Blue: electric brakes
Black: auxiliary power
Both connectors are quite standard and the colors do have meaning they just aren't what you're used to.
