- 40FT EXTRA LONG CABLE – REACH EVERY CORNER OF YOUR TRUCK OR TRAILER: Stop struggling with short test leads that barely reach the engine bay. Our 40-foot power cord lets you connect to the front battery and walk all the way to the tail lights of your F-150, Silverado, Suburban, or 20-foot trailer – with slack to spare. No extensions needed, no moving the vehicle, no second person required. Finally, a circuit tester designed for real-world long-body vehicles.
- ACTIVATE COMPONENTS DIRECTLY – STOP GUESSING, START TESTING: Unlike basic test lights that only tell you if power exists, this power circuit probe lets you send 12V or ground directly to components. Test fuel pumps, window motors, cooling fans, relays, and lights instantly – right at the connector. Hear the relay click, watch the motor spin, see the light glow. You're not just measuring; you're validating functionality. Diagnostic time cut in half.
