Key Features
- Comprehensive 7-Way Testing – Verifies tail lights, brake lights, reverse, turn signals, electric brakes, ground, and auxiliary power for complete confidence
- Color-Coded LED Indicators – Bright, easy-to-read LEDs clearly display which circuits are functioning properly

- Durable Construction – Quality plastic housing with long-lasting LED lights for dependable, repeated use
Features & Benefits
The Curt 7-Wa RV Blade Connector Tester is specifically designed to plug directly into your vehicle’s 7-way RV blade socket. Once connected, it responds to signals generated when you activate your brake pedal, turn signals, running lights, and other functions.
Each LED on the tester is clearly labeled and color-coded to correspond with a specific circuit. When the vehicle socket is delivering proper power, the matching LED illuminates. If a light does not activate, you instantly know which circuit requires attention. This saves time, eliminates guesswork, and makes diagnosing electrical issues far more efficient.
One of the standout advantages of this tester is its integrated resistors for Smart Tow compatibility. Many modern trucks use advanced monitoring systems that detect trailer connection and lighting loads. The built-in resistors ensure accurate readings without triggering false alerts.
Constructed with bright, long-lasting LED lights and durable molded plastic housing, this tester is built for repeated use in real-world conditions. It’s compact enough to keep in your glove box or tool kit, making it an essential part of your towing safety equipment.
This tester fits standard 7-way RV blade connectors, commonly found on full-size trucks and SUVs used for towing RVs, travel trailers, boat trailers, and utility trailers.
If you’re installing new wiring or troubleshooting trailer light issues, this tool quickly helps determine whether the problem is in your vehicle’s wiring or the trailer itself—saving both time and money.
