Works great: External accessory

Works well, immediately showed the plug was misconnected. The hook is too small to hook onto the handlebars, but I don't think you really need one.

Pros
  • Designed so one person can check that the car's wiring harness is installed correctly and all functions work
Cons
  • Requires a socket

Very useful product for towing products and winches

We sell many implements and trailers for horses. It seems that the tow strap always fails on either the car side or the trailer side. With this tester you can quickly determine if there is a line on the side of the vehicle.

Pros
  • Tests all functions of the tractor - ground, brake, direction, backup and auxiliary power
Cons
  • Unreliable

Trailer to tow vehicle wiring made easy!

This is a very valuable asset when there is no one around to help you check the trailer lights and brake connections on your vehicle! Having been disabled twice above the knee I have found this tool to be invaluable, it makes my job easier and I don't have to wheel myself into the back of my truck! It is very easy to use and I would highly recommend it to all DYS and Shade Tree mechanics planning trailer towing vehicle wiring!

Pros
  • Includes 20ft Heavy Duty Extension Lead
Cons
  • Expensive
