If you’re towing with a modern vehicle, you’ve probably already realised that trailer wiring isn’t as simple as it used to be. With today’s vehicles packed full of computer systems and advanced diagnostics, using the wrong wiring setup can quickly turn into a frustrating (and expensive) headache.

Modern Vehicles Need the Right Wiring
As vehicle technology has advanced, so has the complexity of vehicle lighting and electrical systems. Many modern vehicles — particularly European models — emit pulse current for their lighting systems. Unfortunately, this isn’t always compatible with trailer LED lights, which require a constant current to operate correctly.
When the wrong wiring is used, common issues can include:
- Flickering or flashing dashboard warning symbols
- Inconsistent or flashing external lights
- Random computer system fault alerts
These problems aren’t just annoying — they can affect safety and compliance when towing.
Trouble-Free Towing You Can Rely On
Patch Cables Australia wiring harnesses are designed to eliminate these issues. By isolating the trailer electrics from the vehicle’s sensitive computer systems, they help ensure smooth, reliable operation without triggering faults or errors.
The result? Confidence and peace of mind every time you hitch up and head off.
Ideal for Everyday and Long-Distance Towing
Whether you’re towing locally or planning longer trips, especially in hotter conditions or over long distances, reliable wiring is essential. A quality wiring harness helps ensure your trailer lights work properly at all times — day or night.
With Patch Cables Australia, you can tow knowing your vehicle’s electronics are protected and your trailer lighting is operating exactly as it should.
