Why You Need This

The charging system is critical in any EFI conversion, yet it's often overlooked until problems arise. Without proper alternator integration, you'll face voltage regulation issues, ECU resets under load, and potential damage to sensitive electronics. This becomes particularly problematic in LS swaps where you're mixing modern ECU technology with older chassis wiring.

This Bosch-compatible harness is essential for builds using popular alternators like the Bosch 0124 series commonly found on late-model LS engines, or aftermarket high-output Bosch-style units. The 200mm length provides flexibility for various engine bay configurations whilst maintaining the clean, professional finish that separates a proper conversion from a bodged installation. We see this regularly in LS-swapped E30s, E36s, and Mk1/Mk2 Golfs where space is tight but alternator positioning is critical.

ECU & System Compatibility

Designed specifically for the Haltech Nexus R5 Universal V8 terminated harness (HT-186200). This integration ensures your Nexus ECU can properly monitor alternator output and manage the charging system as part of the overall engine management strategy.
