Trailer Connector
& Brake Force Testing
Having issues with your trailer lights, brakes, or charging system? We provide complete 7-way trailer connector testing and brake force diagnostics to ensure your trailer is operating safely and reliably.
We inspect all seven circuits on the
7-pin connector:
• Running Lights (Tail/Marker)
• Left Turn Signal & Brake
• Right Turn Signal & Brake
• Ground Connection
• Electric Trailer Brake Output
• Reverse Lights (Backup)
• 12V Auxiliary Power (Charging)
In addition to verifying each circuit, we perform brake force testing to ensure your trailer brake controller is delivering proper voltage and current to the brakes—critical for safe towing and stopping distance.
Whether you’re hauling equipment or hitting the open road, don’t take chances with faulty connections. We’ll make sure your tow vehicle and trailer are communicating properly before you hook up and go.
