Reliable Way To Test Your Vehicle's Wiring

When I tried this automotive tester, it accurately diagnosed my wiring issues in seconds. The LED lights make it easy to read, and its compact size is perfect for on-the-go use. The only down-side is that it only tests 4-way flat connectors.

Pros
  • Accurate, easy-to-use LED lights, compact size
Cons
  • Only tests 4-way flat connectors

Excellent 4 wire trailer lighting tester

Good tester, use it all the time to test trailer wiring on cars and trucks with 4 pin wire connectors combined with a 7 to 4 adapter and you can check Lighting on 7-pin systems

Pros
  • Spare parts
Cons
  • Some faults

Bad Internal Connections

This worked to test the taillights/brakes but the connections for the turn signals were very bad. Sometimes I could get them to glow by bending the plug, but I couldn't even get two consecutive flashes to work. I ended up with a 57505 Curt Manufacturing 57505 12 volt flat blade circuit tester that worked great with no issues. (And this works for both four- and five-pin connectors.)

Pros
  • Automotive
Cons
