CAN-Bus Extension Harness - 4ft.

The MSD IGNITION CAN-Bus Extension Harness – 4ft is a precision wiring assembly designed to extend 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. MSD IGNITION's 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. The harness is compact enough to route alongside existing engine bay wiring without requiring additional conduit or management, while the standard connectors ensure compatibility with OEM and aftermarket MSD ignition modules and engine controllers that support CAN-Bus protocols.

This extension 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, turbocharged conversions, or multi-vehicle data logging setups rely on quality CAN-Bus extensions to maintain real-time engine parameter visibility without repeating expensive wiring harness work.

MSD IGNITION is the industry standard in electronic ignition control and engine management wiring for circle-track racing, street performance, and professional tuning shops. Their CAN-Bus harnesses are engineered to OEM quality standards, ensuring long-term reliability in high-vibration and temperature-variable engine compartments. The MSD 7784 extension pairs with MSD digital ignition systems, standalone EFI controllers, and professional engine data loggers that communicate over CAN-Bus networks.
