CAN-Bus Extension Harness - 4ft.

The MSD IGNITION CAN-Bus Extension Harness – 4ft is a precision wiring assembly designed for extending CAN-Bus communication lines in modern ignition and engine management systems. This 4-foot extension harness simplifies installation in applications where factory wiring routes don't align with component placement, eliminating the need for splicing or custom fabrication of critical diagnostic lines.

CAN-Bus (Controller Area Network) harnesses carry bidirectional communication signals between engine control modules, ignition systems, and data logging equipment. The MSD IGNITION extension harness maintains signal integrity across the 4-foot run through properly shielded conductors and OEM-spec connectors, ensuring no data degradation or noise interference. Its compact design allows for routing alongside existing engine bay wiring without requiring additional conduit or management.

This extension harness is essential for custom engine builds, standalone ECU conversions, and performance tuning applications where the ignition module or data acquisition unit must be remotely mounted away from the engine controller. The 4-foot length accommodates mid-engine, rear-mounted, or chassis-mounted control systems while keeping harness routing clean and protected. Technicians performing engine swaps or turbocharged conversions will find this harness particularly beneficial.
