Review: Fast installation and cheap - It took a while to match the wires to the trucks wires but everything works amazing. It’s got plenty of wire and looks sturdy . Installation took about 4 mins once we got the wiring matched . Took it on a 400mile trip with no issues !
Review: Great replacement connectors. - As all Chrysler Dodge RAM owners know, wiring and electrical connectors are not their strong suit. My 2015 RAM 2500 gives off turn signals, stop light, and parking light codes weekly. I traced the problems to the two interconnects in the tail light circuits. I've replaced the worst (Left side) with these new connectors and they work great. Now I'm getting codes for the Right side. I ordered enough connectors to do that side so hopefully that will cure some of the problems. I've owned several Chryslers and there has been many electrical issues. Three Hondas and four Toyotas that I have owned with thousands of miles have never had a single electrical circuit issue. Hmm.

### ⭐⭐⭐⭐ Good connector, check wire coloring carefully
*by S***E on March 14, 2026*

Good connector. However, check wire coloring carefully! In my case, most colors matched expected, except the 10ga black wire went to 12v positive post (aux power) and the 14ga red wire was backup. The standard is heavy red is 12v+ and light green is backup, so use an ohmmeter to see how yours is wired.
