Standard Ignition HR-139 Horn Relay

Horn Relay for Classic Oldsmobile Applications

Standard Ignition HR-139 is a 12-volt horn relay built for select classic Oldsmobile vehicles and related HVAC relay applications that require a bracketed, 4-terminal relay design. It uses a rectangular 2-connector layout with male and female connector genders, plus screw and blade terminal types for the specified applications.

Compatible With 1969-1978 Oldsmobile 98, Custom Cruiser, Cutlass, Cutlass Calais, Cutlass Salon, Cutlass Supreme, Delta 88, Omega, Starfire, and Toronado applications where the listed relay configuration is required. Standard Ignition HR-139 is also a direct reference point for restoration and electrical repair work on these vehicles.

Key Features

• 12-volt relay for automotive electrical systems
• Rectangular housing with 2 connectors
• 4-terminal design with screw and blade terminals
• Mounting bracket included for specified applications
• Composite housing helps protect the relay in under-hood heat and harsh conditions
• Brass or copper contacts are used where specified for wear resistance
• Manufactured under TS16949 and ISO9001 certified processes

Detailed Description

The Standard Ignition HR-139 horn relay is built to meet the electrical and physical requirements of select Oldsmobile platforms from 1969 through 1978. The relay’s composite housing is made to withstand elevated temperatures and demanding engine-bay conditions, while the contact design uses brass or copper materials where specified to support long-term electrical performance. Standard Ignition controls production from component selection through finished assembly to maintain consistent part quality.

This part cross-references Bosch 16132 for the same application. It also aligns with restoration and service needs on Oldsmobile 98, Cutlass, Delta 88, and Toronado models where the original relay style and bracketed mounting are required. Standard Ignition HR-139 is a practical replacement for vehicles needing a 12V relay with the listed connector and terminal layout.

What It Helps Fix

• No horn operation caused by relay failure
• Intermittent horn function from worn relay contacts
• Electrical issues related to heat-damaged relay housings
• Mounting problems when the original bracketed relay is missing or damaged
• Connector mismatch during relay replacement on listed Oldsmobile applications

Installation Notes and Tips

Verify the connector shape, terminal count, and mounting style against the original relay before installation. This relay uses a 4-terminal screw and blade configuration with a rectangular housing, so matching the existing wiring and bracket location is important for proper fitment. Confirm the vehicle’s relay application by year, model, and notes, especially on Oldsmobile HVAC automatic temperature control relay applications and Toronado listings with 4-terminal requirements.
