Honda B/D/H/F Series Coil-on-Plug Wiring Diagram
In this guide, I’ll show you the universal wiring diagram for converting any Honda B, D, H, or F series engine to coil-on-plug using Honda D17 or K-series coils. In the accompanying video, I’m doing this conversion on a 2001 Honda CR-V with a B20z engine, but this same wiring applies to all Honda B, D, H, and F series engines since they all use the same distributor harness setup.
