The 10-821614-6Y is a dual ignition harness used on Continental aircraft piston engines. It routes high-voltage output from both magnetos to the engine’s spark plugs, ensuring redundant ignition for all cylinders.

It is part of the D6-3000 ignition system family, designed to maintain reliable spark delivery under high temperature, vibration, and oil exposure conditions in certified aircraft engines.

The “Y” suffix indicates the yellow color coding, typically used for identification and routing distinction between ignition systems or magneto sides.

Key features include:

Dual magneto ignition harness (full engine coverage)
Yellow-coded lead assembly for identification (Y variant)
High-voltage insulated ignition cables
Pre-terminated spark plug and magneto connectors
Designed for Continental D6-3000 ignition systems
Heat-, oil-, and vibration-resistant construction
Maintains redundant ignition for engine safety
Precision-routed wiring for correct cylinder firing order
Compatible with specific Continental piston engine configurations (IPC-dependent)
Used in certified aircraft engine maintenance and overhaul procedures
