SPAL Harness Adapter for Brushless Fans - SBL-YAZ-PT10-PKG

The SPAL SBL-YAZ-PT10-PKG Harness Adapter for Brushless Fans is the dedicated wiring solution designed specifically to connect SPAL brushless electric cooling fans — including the Plus and Nuova series — to a vehicle's power source and control system. If you're building or upgrading a SPAL brushless fan installation and need a properly engineered pigtail harness to complete the circuit, this is the OEM-matched adapter made for the job. It pairs with the SPAL SBL-TS-HARN main harness, making it a critical link in any multi-fan brushless cooling setup.

Key Features & Benefits

• Purpose-Built for SPAL Brushless Fans: Engineered specifically for SPAL SBL series brushless fans (Plus and Nuova series), ensuring a secure, correct-fit electrical connection without modification or adaptation guesswork.
• Yazaki 4-Pin Connector: Uses a Yazaki 4-pin connector interface — the same connector type used on SPAL's SBL brushless fan motors — for a reliable, weatherproof connection that holds up in demanding underhood environments.
• Designed to Work with SBL-TS-HARN: This pigtail harness connects directly to the SPAL SBL-TS-HARN main temperature-sensing harness, integrating cleanly into the full SPAL brushless fan wiring ecosystem.
• Scalable Multi-Fan Installations: When running multiple SPAL brushless fans off a single SPAL sensor, each fan requires its own SBL-YAZ-PT10 pigtail — and only one sensor and one SBL-TS-HARN are needed for the entire system. Up to 12 fans can be run from a single SPAL sensor, making this harness essential for larger cooling configurations.
• Eliminates Improvised Wiring: Using the correct SPAL-spec harness adapter removes the risk of incorrect connections, voltage drop issues, or PWM signal errors that can arise from improvised or generic wiring solutions.
• Clean, Professional Install: Plug-and-play design keeps wiring tidy and reduces install time, which is especially valuable in tight engine bays or race/performance builds where clean routing matters.

Fitment

The SPAL SBL-YAZ-PT10-PKG is not vehicle-specific — it is a universal harness adapter designed to work with SPAL SBL brushless fans (Plus series and Nuova series) across any automotive, off-road, racing, or performance application where these fans are installed. If you are running SPAL brushless electric fans and need to connect them to the SPAL SBL-TS-HARN controller harness, this pigtail is the required link. One harness adapter is needed per fan; for multi-fan setups (up to 12 fans), each additional fan requires its own SBL-YAZ-PT10-PKG. This adapter is not intended for SPAL's brushed (standard) fan lineup — verify your SPAL fan model is an SBL brushless unit before ordering.

What's in the Box

The SBL-YAZ-PT10-PKG is sold as a complete pigtail harness kit (PKG) ready for installation. The package includes the Yazaki 4-pin pigtail harness adapter designed to connect a single SPAL SBL brushless fan to the SBL-TS-HARN system harness.

Frequently Asked Questions

Q: How many SBL-YAZ-PT10-PKG harnesses do I need for my SPAL brushless fan setup?

A: You need one harness adapter per fan. If you're running two SPAL brushless fans, you'll need two of these pigtails. Importantly, you only need a single SPAL sensor and a single SBL-TS-HARN main harness regardless of how many fans you run — up to 12 fans can operate off one SPAL sensor.

Q: What SPAL fan series does this harness adapter fit?

A: The SBL-YAZ-PT10-PKG is designed for SPAL SBL brushless fans, specifically the Plus and Nuova series. It is not intended for SPAL's traditional brushed fan motors. Check that your fan model includes "SBL" in the part number before ordering.

Q: What does this harness connect to on the controller side?

A: This pigtail harness is designed to connect to the SPAL SBL-TS-HARN main temperature-sensing harness. The SBL-TS-HARN (sold separately) is the central harness that interfaces with the temperature sensor and power supply; the SBL-YAZ-PT10-PKG bridges that harness to each individual brushless fan.

Q: Is this item in stock and ready to ship?

A: Yes — the SPAL SBL-YAZ-PT10-PKG is a regularly stocked product at ThreePiece.us, not a special order item. It ships free on every order.
