Review: anything - good quality value for money works well for my car
Review: Well built and easy to customize if needed at a reasonable price - I’ve never run into this type plug now I’m seeing them a lot I’m referring to the mini plug it was perfect mate to a fuel trailer we use on the farm it has to be moved on two lane county roads between properties to supply diesel fuel to various tractors the owner has been relying on a simple SMV sign and the lights on the truck pulling it so I figured there had to be an adaptor and sure enough found it it seems well built and now we have trailer brakes, turn signals brake lights and soon the 12 volt pump will be connected or if decided a battery installed on the trailer it will have a charge line from the truck towing it I noticed the seller has many different configurations available so I may be looking for another connector in the future I know now where to look

### ⭐⭐⭐⭐⭐ Must-Have Tool for Quick Trailer Diagnostics
*by J***. on May 2, 2025*

This 7 Pin Trailer Wiring Tester was exactly what I needed to troubleshoot a wiring issue on my Dodge truck. The LED indicators are bright and easy to read, making it simple to see which circuits are working properly and which weren’t. It saved me a lot of time by helping me quickly identify the problem without having to dig into the wiring blindly. The build quality feels solid, and it plugs right into the trailer connector with a secure fit. If you tow frequently or just want peace of mind before hitting the road, this is a great tool to have in your glove box or toolbox. Highly recommended for anyone who deals with trailers or does their own wiring checks!
