Spool Performance B58 G2 / S58 Plug and Play Motiv Reflex Plus Harness SP-B582S58-PPRPH

Spool Performance B58 Gen 2 / S58 Plug-and-Play Reflex+ Harness

The Spool Performance Plug-and-Play Reflex+ Harness is the cleanest and most efficient way to install your Motiv Reflex+ system on B58 Gen 2 and S58-powered vehicles—completely eliminating the need for cutting, splicing, or depinning factory wiring.

Designed with simplicity and reliability in mind, this harness provides a true OEM-style integration while dramatically reducing installation time and complexity.

Simplified Installation – No Cutting, No Guesswork

Traditional Reflex+ installations often require tapping into the DME or working inside the tight passenger-side footwell—especially challenging on mild-hybrid vehicles with limited space.

This plug-and-play solution removes those obstacles entirely:

• No wire cutting or splicing
• No depinning connectors
• No DME pinning required
• Fully reversible installation

Simply plug in the harness and you’re ready to go.

Modular Design – Smarter Than Full Harness Replacements

Unlike full replacement harnesses, the Spool system uses a modular sub-harness design:

• Connects directly to the existing Motiv Reflex+ flying lead harness
• Replaces only the required signal and power sub-harness
• Eliminates the need for posi-tap connectors

This approach keeps your setup clean while avoiding unnecessary complexity.

Save Time and Money

By eliminating the need for a full custom harness, this solution helps you:

• Avoid spending $600+ on custom wiring setups
• Reduce installation time significantly
• Maintain a cleaner, more professional engine bay

Built for OEM-Level Integration

Every aspect of this harness is designed to maintain factory-like fitment and reliability while supporting high-performance fueling control systems.

Perfect for enthusiasts and professional installers looking for a reliable, clean, and efficient Reflex+ integration.
