Simplify automotive relay installation and replacement with the Quality Mobile Video BRS16 prewired relay socket. Designed for standard Bosch-style five-pin SPDT relays, the socket provides conventional terminals for pin 30 common, pin 87 normally open, pin 87a normally closed, and coil pins 85 and 86. Color-coded 16-gauge leads make circuit identification easier, while fully insulated terminals help prevent accidental contact and short circuits. Integrated male and female slide tracks allow multiple BRS16 sockets to interlock side by side for clean, organized multi-relay installations. The replaceable plug-in design is ideal for automotive lighting, car audio, alarms, accessories, custom vehicles, race cars, and other 12-volt electrical projects.

Relay Sockets – Complete Guide
What is a Relay Socket?
A relay socket (also called a relay base or relay holder) is the plastic base that a relay plugs into. It provides secure electrical connections and makes it easy to install, replace, or service the relay without cutting or soldering wires directly to the relay pins.
Why Use a Relay Socket?
- Makes relay replacement quick and tool-free
- Protects the relay terminals
- Allows for cleaner, more professional wiring
- Easier to add fuses, diodes, or resistors
- Enables modular and expandable designs
Main Types of Relay Sockets
| Type | Size | Pins | Interlocking | Best For |
|---|---|---|---|---|
| Micro Relay Socket | Small | 5 | Yes/No | Tight spaces |
| Full-Size Relay Socket | Standard | 5 | Yes/No | High current, custom builds |
| ISO Relay | Large | 4/5 | Usually No | OEM replacements |
Key Features Explained
- Interlocking (BRSPC, BRS14PT, BRS14E, BRS12E, BRS14MR, BRSCP) – Can be connected together to form neat relay banks
- Non-Interlocking (BRSC, BRSP) – Individual sockets for flexible spacing
- Socket Only vs With Contacts (BRSCN comes with terminals)
- Solder Tab (BRSS) – Best for high-vibration environments
Standard 5-Pin Relay Socket Pinout
- 30 – Power Input (Common)
- 87 – Normally Open Output
- 87a – Normally Closed Output
- 85 – Coil Ground
- 86 – Coil Positive (+12V trigger)
Common Applications
- Custom car audio systems
- Auxiliary lighting (LED bars, fog lights)
- Cooling fans & fuel pumps
- Winches and horns
- Marine and race car electrical systems
Pro Tip: Always use a fuse on Pin 30 and consider dielectric grease for better corrosion protection.
Pro Tips for Using Relay Sockets
- Always use the correct wire gauge — Match wire size to your current load (e.g., 12–14 AWG for 20–30A applications).
- Add a fuse on Pin 30 — This is critical for safety. Place an appropriately rated fuse as close as possible to the power source.
- Use dielectric grease — Apply a small amount on the relay pins and inside the socket to prevent corrosion and improve electrical contact.
- Choose solder tab sockets for high vibration — For race cars, off-road vehicles, or marine use, the BRSS (solder tab version) offers superior vibration resistance.
- Take advantage of interlocking sockets — Models like BRSPC or RS102E allow you to create clean, professional-looking relay banks with minimal space.
- Label your relays and wires — Makes future troubleshooting much easier.
Bonus Tip: When using crimp terminals, always use a quality crimping tool and double-check for solid connections before final installation.
