Bosch 0986AH0300 Multi-Purpose Relay

Bosch Micro Relay for OE-Style Electrical Control

The Bosch Micro Relay is a 12-volt, 20-amp multi-purpose relay built for continuous duty in a compact OE-style format. It uses a 4-terminal blade design with a single male/female connector interface, making it a practical replacement for a wide range of Ford, Hyundai, Subaru, Saab, and other vehicle applications.

Part number 0986AH0300 is a direct-fit electrical relay solution for drivers and technicians servicing relay-controlled circuits in vehicles such as the Ford F-150, Ford Focus, Hyundai Elantra, and Subaru Forester. Bosch 0986AH0300 is specified for OE mounting and is designed to match factory relay layouts where a 4-pin micro relay is required.

Key Features

• 12-volt Bosch Micro Relay for multi-purpose electrical circuits
• 20-amp amperage rating for relay-controlled loads
• Continuous duty construction for sustained operation
• 4 blade terminals with OE mounting type
• Polymer cover material for compact underhood or cabin relay locations
• Single connector design with male/female connector gender

Product Details

This Bosch multi-purpose relay is engineered as an OE-style electrical switching component for a broad range of late-model and older vehicles. The micro relay format helps maintain factory fitment in relay panels and junction boxes, while the 4-terminal blade layout supports straightforward replacement of worn or failed relays. Bosch 0986AH0300 is a practical choice when restoring proper circuit control in applications that rely on a compact 12V relay.

This part cross-references Bosch OE-style relay applications such as 0025428419 and 0025451119 for the same application.

Common Uses

• Restoring power to a circuit that no longer switches on
• Replacing a relay with intermittent electrical operation
• Addressing accessory, lighting, or body-control relay faults
• Correcting clicking, sticking, or non-responsive relay behavior
• Servicing OE relay panels in Ford, Hyundai, Subaru, and Saab vehicles

Installation Notes

Verify the relay cavity, terminal count, and connector style before installation. This Bosch micro relay uses blade terminals and OE mounting, so it should be matched to the factory relay location and circuit specification. Confirm the vehicle’s voltage and amperage requirements before replacing the original relay. For fitment examples, this part fits 2004-2008 Ford Focus, 2001-2014 Hyundai Elantra, and 1998-2008 Subaru Forester in relay applications listed as multi-purpose relay.

Quality Assurance

Bosch supplies OE-level electrical components for automotive service applications, and this relay follows the same compact micro-relay format used in factory systems. Part number 0986AH0300 is built for continuous-duty operation and OE-style replacement use across the listed vehicle applications.
