Questions & Answers

The conector is circular rather than flat, and it fits into a circular hole. Is this for a round PIN connection, a spade, or a flat 7-pin connector? pin unit? A round hole with six flat pins and a round center pin is present in my Tundra. Thank you in advance for your time and trouble, as well as the information! ?

Yes, this is for a seven-way flat; the pin models are for big rigs or specialty trailers.

If you own a 7-inch screen, this is a must-have
5/5

This is the pin connector you'll need. When I bought a new snowmachine trailer, the shop kept telling me that my plug was bad. When I got home, I checked for myself and discovered that the plug's pins had been bent. Straightened them out, then used this tester to make sure everything was in working order. It's in the glove compartment of my car. I use it every time I hook up to make sure the plug is working first, and then I know it's not the plug if the lights aren't working.

Poor execution of a great idea. The sound is not loud enough to be heard over the sound of a truck running.

ONE TEST WAS INVALID, SO I TRYED IT ON ANOTHER VEH, AND SEVERAL OTHERS NEED TO BE REPLACED.

This is a fantastic idea
3/5

The quality is poor. There are two issues - When I got it, the casing was cracked. There's no need to be concerned. However, the first time I used it, it fell apart. It turned out that there was no set screw holding it together, so it disintegrated in the socket - It's extremely difficult to remove it without causing damage. When I was plugged in, I was able to work and I appreciated the audible feature - Checking the trailer circuits from the vehicle's interior is a fantastic idea. My Prodigy brake controller didn't seem to work with it - The brake controller didn't recognize it was connected, and the brake control LED light on this unit would simply blink slowly, but there was no explanation - I believe the LED should remain lit at all times. This is something that the instructions aren't very clear about. I returned it, primarily due to issues with quality control, and Amazon's return policy, as always, is fantastic!.

However, it performs as expected
3/5

In a manufacturing environment, it's a little difficult to hear, but it works fine.
