The SeaSense EZ Troubleshooter II is a professional-grade circuit tester designed to quickly diagnose electrical issues in 4-way flat trailer wiring systems. This essential diagnostic tool plugs directly into your vehicle's standard 4-prong flat towing connector to verify proper power delivery to trailer lights without the need for an actual trailer connection.
Key Features:
This circuit tester is ideal for boat trailers, utility trailers, and small cargo trailers using standard 4-way flat wiring systems. The pass-through design means you can verify circuits before each trip without disconnecting the tester, saving valuable time during pre-tow safety checks. Essential for anyone who regularly tows trailers and needs to quickly identify wiring faults at the vehicle connector.

Satisfied. I have only one sour thing to say: the parts I received were made in China. I hope they last as long as the originals which was 330,000 miles.

Great prices! Had exactly what I was looking for, for $20 less than anywhere else even with the shipping cost added in.
