Product Description

The Rywire RY-CHARGE-HARNESS-K is a dedicated charge harness designed for Honda K-Series engine wiring setups. It provides a clean, high-capacity electrical path from the battery/fuse box to both the starter motor and the alternator, ensuring proper charging and reliable starting in modified or swapped vehicles. This harness is intended for use specifically with Rywire K-Series engine harnesses, where factory-style charging leads are either removed or not included in the main loom.

Featuring two 8 AWG cables, this harness supports the elevated current demands of high-performance builds and simplifies wiring changes often encountered in engine swap projects. Rather than creating your own heavy-gauge paths or splicing into factory harnesses, the Rywire charge harness gives a structured and robust solution that integrates directly with the Rywire engine harness architecture. It's a valuable add-on for anyone building a K-Series swap harness or upgrading charging/starter wiring reliability.
