## Customer Reviews

### ⭐⭐⭐⭐⭐ 5 prong trailer plug
*by R***2 on April 18, 2024*

Ended up not needing to use but the whites& blue wires were opposite side of original trailer plug, not sure if white ground on plug would have matched ground wire on truck wiring.

### ⭐⭐⭐⭐⭐ Good fit
*by S***A on May 24, 2024*

Came as advertised.

### ⭐⭐⭐⭐⭐ Great product
*by M***. on January 12, 2024*

Keep this with me all summer when I am trailing as a backup incase something goes wrong with the one on the trailer
