Comments

MikeL: Used it to check if the brakes on my truck for the seven pin connector was working. Easy to use and wish I had one many years ago.

Shawn Mielke: Super easy and economical. Compact as well. Toss it in your glove box, center console or tool box. Great for troubleshooting electrical trailer wiring problems.

Tony K.: A lot of reviews stated that this works in only one position, where the lights have to be viewed from the bottom of the tester, not so, a little dielectric grease on the female terminals helps it slide into place perfectly, very easy to read, I tested coth the 7 wire and 4 wire flat ends, works perfectly.

Matthew Tyler Johnson: I sell trailers for a living and every time I hook up a new trailer for a customer, I want to make sure all the lights work before they drive away. Every so often the lights will not work, so I use this immediately to determine if the problem is in the customer's vehicle first. Works great! My only wish is that the LED indicators were on both sides due to some trucks having the plug upside down.

Eddie J D: Works great for the source vehicle. Lets you know if the female/source side of the wiring is good. This will not let you know if the wiring on the trailer has issues. Lights are easy to see and makes testing much easier than trying to hold the spring loaded cover and holding the probes on a voltmeter.

Camper: The lights are on the wrong side, you have to get on your knees and look up to check lights to see if connections are working
