The 10-821614-6 ignition dual harness is an aircraft engine ignition wiring assembly used on Continental piston engines. It routes high-voltage output from both magnetos to all engine spark plugs, ensuring full dual-ignition redundancy.

It uses 3/4-inch magneto connection fittings, making it compatible with D6-3000 ignition system configurations depending on engine model.

The harness is built to withstand continuous exposure to heat, oil, vibration, and high voltage discharge in aviation engine environments.

Key features include:

Dual magneto ignition harness (full cylinder coverage)
3/4 in magneto connection fittings
High-voltage insulated ignition leads
Pre-terminated spark plug and magneto terminals
Designed for Continental D6-3000 ignition system configurations
Heat, oil, and vibration resistant construction
Maintains redundant ignition for engine safety
Routed for correct cylinder firing order
Compatible with specific Continental piston engine models (IPC-dependent use)
Used in certified aircraft engine maintenance and overhaul procedures
