SPAL SBL-TS-HARN Jumper Harness for Brushless Fans

The SPAL SBL-TS-HARN is a jumper harness that bridges the SBL-YAZ-PT10 harness adapter to a SPAL temperature sensor, completing the automated cooling control circuit for SPAL brushless fan installations. Equipped with a Deutsch DT06-4S 4-socket connector, the SBL-TS-HARN carries the temperature sensor signal to the fan control system and supports control of up to 12 fans per harness. One SBL-TS-HARN is sold per package.

How the SBL-TS-HARN Integrates into the SPAL Brushless Fan System

A complete SPAL automated brushless fan cooling setup consists of three components working together. The SBL-YAZ-PT10 harness adapter connects at the fan motor, providing the power leads and PWM signal wire. The SBL-TS-HARN jumper harness then bridges that adapter to a SPAL temperature sensor, routing the sensor signal into the control circuit. Together, the SBL-YAZ-PT10, SBL-TS-HARN, and a compatible SPAL temperature sensor create a complete, automated cooling setup that adjusts fan speed in proportion to coolant or ambient temperature without requiring a separate standalone controller module.

This integration is particularly well-suited to multi-fan radiator setups in performance vehicles, towing builds, or any application where consistent thermal management across a bank of fans is required. Because a single SBL-TS-HARN can coordinate control of up to 12 fans, large multi-fan arrays can share a single temperature input without needing additional signal wiring for each motor.

Deutsch DT06-4S Connector

The SBL-TS-HARN uses a Deutsch DT06-4S 4-socket connector at the temperature sensor interface. Deutsch DT-series connectors are an industry standard in motorsport, agriculture, heavy equipment, and performance automotive wiring. They are engineered for high vibration resistance, robust sealing against moisture and contaminants, and secure locking under harsh underhood conditions. The DT06-4S designation indicates a 4-position socket-side connector from the Deutsch DT series. This connector type is widely recognized and its mating plug is readily available from electrical supply sources, which simplifies any future serviceability or modification of the harness.

The Deutsch DT connector contrasts with the Yazaki connector used on the fan-side SBL-YAZ-PT10 adapter. Each connector type serves its specific role: the Yazaki connector interfaces directly with the SPAL fan motor housing, while the Deutsch DT06-4S interfaces at the temperature sensor side of the jumper harness.

Frequently Asked Questions

What is the difference between the SBL-YAZ-PT10 adapter and the SBL-TS-HARN jumper harness?
The SBL-YAZ-PT10 is the fan-side harness adapter that connects directly to the SPAL brushless fan motor via a Yazaki connector and provides the power leads and PWM signal wire. The SBL-TS-HARN is a separate jumper harness that connects the SBL-YAZ-PT10 adapter to a SPAL temperature sensor, enabling automatic temperature-based fan speed control. They are two distinct components that work together in the same system.

Do I need both the SBL-YAZ-PT10 and the SBL-TS-HARN?
If your goal is fully automated temperature-based fan control, yes, both are required along with a compatible SPAL temperature sensor. The SBL-YAZ-PT10 provides the fan motor connection, and the SBL-TS-HARN bridges that adapter to the temperature sensor. Without the SBL-TS-HARN, the system does not have the sensor input needed for automatic speed control.

Is the temperature sensor included with the SBL-TS-HARN?
No. The SBL-TS-HARN jumper harness is sold without a temperature sensor. A compatible SPAL temperature sensor must be purchased separately to complete the automated cooling circuit.

How many fans can one SBL-TS-HARN control?
A single SBL-TS-HARN jumper harness supports control of up to 12 fans. This makes it well-suited for multi-fan radiator or intercooler setups where several brushless fan motors need to operate from a common temperature input.

What is the Deutsch DT06-4S connector and why is it used?
The Deutsch DT06-4S is a 4-socket connector from the Deutsch DT series, which is an industry-standard connector family used across motorsport, heavy equipment, marine, and performance automotive applications. It provides a secure, weatherproof, vibration-resistant connection that is well-suited to underhood environments. Its widespread use also means mating connectors and repair terminals are readily available from electrical suppliers.

How does the Deutsch DT connector on the SBL-TS-HARN differ from the Yazaki connector on the SBL-YAZ-PT10?
The Yazaki connector on the SBL-YAZ-PT10 is specifically matched to the connector housing on the SPAL brushless fan motor. The Deutsch DT06-4S connector on the SBL-TS-HARN is the interface point for the temperature sensor side of the circuit. Both connector types are automotive-grade and weatherproof, but they serve different connection points within the system and are not interchangeable.

Is the SBL-TS-HARN compatible with non-SPAL brushless fans or third-party temperature sensors?
The SBL-TS-HARN is designed and validated for use within the SPAL brushless fan wiring system, specifically with the SBL-YAZ-PT10 adapter and SPAL temperature sensor. Compatibility with third-party fans or sensors depends on whether those products match the connector pinout, signal type, and voltage requirements of the SPAL system. SPAL does not warrant the harness for use outside of its intended system.

What does a typical installation look like for the SBL-TS-HARN?
In a typical setup, each SPAL brushless fan is connected via its own SBL-YAZ-PT10 adapter harness. The SBL-TS-HARN jumper harness then connects those adapters to the SPAL temperature sensor. The temperature sensor is mounted in the coolant passage, radiator tank, or other appropriate location. As coolant temperature rises, the sensor signal travels through the SBL-TS-HARN to the control circuit, which adjusts the PWM signal to each fan accordingly. Refer to the SPAL installation documentation for specific wiring diagrams.

Can I use multiple SBL-TS-HARN harnesses in one vehicle?
Yes. If your installation requires more than 12 fans or includes separate cooling circuits (for example, a primary radiator array and a separate transmission cooler array), multiple SBL-TS-HARN harnesses can be used, each connected to its own temperature sensor and bank of SBL-YAZ-PT10 adapters.
