The CURT 56106 harness features a circuit-protected converter system designed to prevent damage to the vehicle's electrical system in case of a short circuit or overload. If you experience issues with your trailer lights, refer to the following:

Circuit Protected Converter Systems:

This product has been 100% tested under full load and provides internal circuit protection. If a short circuit or overload situation occurs in a trailer lighting circuit, the module is designed to shut the circuit down, allowing no current to flow until the issue is resolved.

• Ti o ba ti trailer lamps are working but the trailer lamps are not working, shut power off to the faulted circuit for a few seconds then try the circuit again.
• Ti lamps do not return to normal function, the fault has not been cleared.

Ti lamps light for a few seconds and then go off:

1. Check ground wire on both the harness and trailer.
2. Check for an overload condition (too many bulbs).

If the circuit fails to light:

1. Check low vehicle fuse.
2. Check for open or broken connections.
3. Check for defective bulbs.
4. Check ground wire on both the harness and trailer.
5. Wa ki o si se atunse kukuru kan.

Note: Using a tester can help confirm system function. If problems persist, see your installer for corrective action. Do not use the product while towing if it is not functioning properly.
