Standard Ignition RY-364 Tail Light Relay

Tail Light Relay for Subaru Applications

Standard Ignition RY-364 is a 12-volt tail light relay built for electrical control in select Subaru vehicles. It uses a female square connector, 4 male blade terminals, and a 20 amp amperage rating for relay function in the tail light circuit.

Compatible With 1990-1998 Subaru Legacy and 1993-1998 Subaru Impreza tail light relay applications, this part number is a direct-fit electrical replacement for the listed vehicles. Standard Ignition RY-364 is a practical choice when diagnosing rear lighting relay faults on Subaru Impreza and Subaru Legacy models.

Key Features

• Tail light relay for 12 V electrical systems
• 20 A amperage rating
• Female connector with square shape
• 4 male blade terminals
• Relay function only
• Continuous duty: No
• Mounting bracket not included

Detailed Description

Standard Ignition RY-364 is designed for tail light relay service in the specified Subaru fitments. The relay uses a square female connector and blade-style terminals to match the original electrical interface, helping restore proper circuit switching for rear lighting operation. If you are replacing a failed tail light relay on a Subaru Legacy or Subaru Impreza, RY-364 provides the correct electrical specifications for the listed applications.

This part cross-references Eastern Catalytic 20346 for the same application.

Common Issues This Part Can Address

• Tail lights that do not switch on consistently
• Intermittent rear lighting operation
• Relay-related electrical faults in the tail light circuit
• Loss of proper voltage switching to the rear lamps
• Failed relay contacts causing lighting malfunction

Installation Notes and Tips

Verify connector shape, terminal count, and voltage before installation. Confirm the relay location in the vehicle’s electrical system and inspect the surrounding harness for corrosion, heat damage, or loose terminals. For best results, compare the removed relay to Standard Ignition RY-364 before installation.

Quality Assurance

Standard Ignition is a recognized name in replacement electrical components, and this relay is built to match the listed fitment and electrical specifications for Subaru tail light relay service.
