Featuring a Yazaki connector on the fan side and heavy-duty 10 AWG power leads (red positive, black negative) alongside a white PWM signal wire, the SBL-YAZ-PT10 provides a clean, reliable wiring interface for SPAL Plus Series and Nuova Series brushless fans. One adapter is required per fan.\u003c\/p\u003e\n\n\u003ch4\u003eHow Brushless Fan Wiring Works\u003c\/h4\u003e\n\u003cp\u003eSPAL brushless fans differ from conventional brush-type fans in how they receive power and speed commands. A brushless motor requires a dedicated electronics package that interprets a Pulse Width Modulation (PWM) signal to vary fan speed smoothly and efficiently. The \u003cstrong\u003eYazaki connector\u003c\/strong\u003e on the SBL-YAZ-PT10 plugs directly into the mating connector on the fan motor housing, ensuring a weatherproof, vibration-resistant electrical connection without any splicing or crimping at the fan itself.\u003c\/p\u003e\n\u003cp\u003eThe 10 AWG power wires are sized to handle the current demands of a high-output brushless fan without voltage drop. Thicker wire gauge means less resistance over longer routing runs, which matters in engine bays where wiring often travels several feet from the fuse block or relay to the fan. The white PWM signal wire carries a low-current control signal from a temperature controller or fan controller module, allowing fan speed to ramp up and down in response to coolant temperature or other sensor inputs.\u003c\/p\u003e\n\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eThe SBL-YAZ-PT10 adapter is compatible with \u003cstrong\u003eSPAL Plus Series and Nuova Series brushless fans\u003c\/strong\u003e. Both product families use the same Yazaki mating connector at the motor housing, making this adapter the correct interface for either series. If you are installing two brushless fans (a push and a pull setup, or side-by-side dual-fan assemblies), one SBL-YAZ-PT10 adapter is required for each individual fan. The adapters can share a common PWM signal source while each fan runs its own dedicated power circuit.\u003c\/p\u003e\n\u003cp\u003eThis adapter is not designed for SPAL standard (brush-type) fans, which use different connector configurations and do not require a PWM control lead.\u003c\/p\u003e\n\n\u003ch4\u003eWhat's Included\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003e1 x SBL-YAZ-PT10 harness adapter (Yazaki connector, 10 AWG power leads, PWM signal wire)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch4\u003eFull Specifications\u003c\/h4\u003e\n\u003ctable\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eSpecification\u003c\/th\u003e\n\u003cth\u003eDetail\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003ePart Number\u003c\/td\u003e\n\u003ctd\u003eSBL-YAZ-PT10\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eUPC\u003c\/td\u003e\n\u003ctd\u003e816211022584\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eConnector Type\u003c\/td\u003e\n\u003ctd\u003eYazaki (fan side)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWire Gauge\u003c\/td\u003e\n\u003ctd\u003e10 AWG (power leads)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSignal Wire\u003c\/td\u003e\n\u003ctd\u003ePWM signal wire included (white)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWire Colors\u003c\/td\u003e\n\u003ctd\u003eRed (positive), Black (negative), White (PWM signal)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCompatible Fans\u003c\/td\u003e\n\u003ctd\u003eSPAL Plus Series and Nuova Series brushless fans\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSold As\u003c\/td\u003e\n\u003ctd\u003eIndividually (one adapter per package)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eSPAL Automotive\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWarranty\u003c\/td\u003e\n\u003ctd\u003eSPAL standard limited warranty\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003ch4\u003eAbout SPAL Automotive\u003c\/h4\u003e\n\u003cp\u003eSPAL Automotive is an Italian-founded manufacturer with decades of experience producing high-performance electric fans, blowers, and thermal management components.

Both fan families use the same Yazaki mating connector at the motor. It is not compatible with SPAL standard brush-type fans.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eDo I need two adapters for a dual-fan setup?\u003c\/strong\u003e\u003cbr\u003eYes. One SBL-YAZ-PT10 adapter is required per fan. A dual-fan installation (such as push-pull or side-by-side) requires two adapters, one for each motor. Both adapters can share the same PWM signal source while each maintains its own power circuit.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eWhat is a PWM signal and why does a brushless fan need one?\u003c\/strong\u003e\u003cbr\u003ePWM stands for Pulse Width Modulation. It is a digital control signal that varies the on-time of a voltage pulse to communicate a desired fan speed to the brushless motor controller. By adjusting the duty cycle of the PWM signal, a temperature controller can ramp fan speed up gradually as temperatures rise instead of switching the fan fully on or off, which reduces electrical load and noise.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eWhy is 10 AWG wire used for the power leads?\u003c\/strong\u003e\u003cbr\u003e10 AWG wire is sized to carry the higher current requirements of a brushless fan motor without excessive resistance or heat buildup. Thinner wire would create voltage drop over longer routing runs and could become a heat source itself. Using 10 AWG ensures the fan receives full voltage even when wiring runs several feet through the engine compartment.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eWhat is a Yazaki connector?\u003c\/strong\u003e\u003cbr\u003eYazaki is a leading global manufacturer of automotive electrical connectors and wiring harnesses. Yazaki connectors are widely used in factory vehicle wiring for their reliable locking tabs, weatherproofing, and vibration resistance. SPAL uses Yazaki connectors on the Plus Series and Nuova Series fan motors as the primary power and signal interface point.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eIs the SBL-YAZ-PT10 compatible with aftermarket PWM fan controllers?\u003c\/strong\u003e\u003cbr\u003eThe SBL-YAZ-PT10 provides the physical connection and wiring leads needed to interface a SPAL brushless fan with a power source and PWM signal. Compatibility with a specific aftermarket controller depends on whether that controller outputs a PWM signal at the voltage and frequency required by the SPAL brushless motor. Consult the specifications of both the fan and the controller before use.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eHow is the SBL-YAZ-PT10 installed?\u003c\/strong\u003e\u003cbr\u003eInstallation involves plugging the Yazaki connector into the mating connector on the SPAL brushless fan motor, then routing the red positive and black negative 10 AWG leads to a fused power source and chassis ground respectively. The white PWM signal wire connects to the signal output of a compatible temperature controller or PWM fan controller. Always fuse the positive power lead close to the battery or power distribution point.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eIs a temperature sensor or controller included with the SBL-YAZ-PT10?\u003c\/strong\u003e\u003cbr\u003eNo. The SBL-YAZ-PT10 is the fan-side harness adapter only. A temperature sensor and controller are sold separately. For a fully automated temperature-based control setup, the SPAL SBL-TS-HARN jumper harness is used in conjunction with this adapter to connect to a SPAL temperature sensor.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eCan I use the SBL-YAZ-PT10 with a simple on\/off relay instead of a PWM controller?\u003c\/strong\u003e\u003cbr\u003eBrushless fans from SPAL are designed to operate with a PWM control signal for proper speed regulation. Operating without a PWM signal may result in the fan running at a fixed speed or not operating as intended. Refer to SPAL's installation documentation for the specific fan model to confirm the required control method.\u003c\/p\u003e","brand":"SPAL","offers":[{"title":"Default Title","offer_id":45948549562447,"sku":"SPLSBL-YAZ-PT10-PKG","price":51.93,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1062\/7920\/files\/spal-sbl-yaz-pt10-harness-adapter-for-brushless-fans-spal-2.jpg?v=1782224555","url":"https:\/\/www.blackopsautoworks.com\/products\/spal-sbl-yaz-pt10-harness-adapter-for-brushless-fans","provider":"Black Ops Auto Works","version":"1.0","type":"link"}
