ECU Harness Kits With the technology advances in computer diagnostics built-in vehicles today, it is not uncommon for trailer electrics to interfere with such computer systems. Most European vehicles emit pulse current for their lighting which is sometimes not compatible with the LED lighting used on trailers, as they need constant current to operate. Common errors include computer system faults such as flickering symbols on dashboards and flashing external lights. Ark’s range of ECU harness eliminates such problems, suitable for most vehicles but not suitable for vehicles running CANbus systems
