### ⭐⭐⭐⭐⭐ Awesome connection!!
*by  on Reviewed in the United States July 1, 2026*

### ⭐⭐⭐⭐⭐ Just follow the wiring instructions
*by  on Reviewed in the United States August 9, 2026*

I elected to use this plug to wire up some bestview 4 in 1 led bumber inserts into my 2019 grand Cherokee like trailer lights rather than splice into my perfectly good taillight wires. Worked great. I will modify the plug for my application because I want the connection covered but this is a good useable product for its intended functionality or my application.
