The Maypole MP23B 12N Type 7 Pin Plastic Socket is an essential component for reliably connecting your 12V caravan or trailer lighting system to your towing vehicle. Designed for standard lighting functions and conforming to ISO 1724, it ensures a secure electrical link, though users must note that a separate rear gasket (MP99B) is required for proper installation to protect against elements.
12N Type 7-Pin Connection: Provides standard electrical connectivity for common caravan and trailer lighting functions such as indicators, brake lights, and taillights.
Durable Plastic Body: Ensures robust protection for internal wiring and withstands outdoor conditions.
Corrosion-Resistant Brass Pins: Offers excellent electrical conductivity and longevity, reducing the risk of intermittent connections.
Screw Terminals: Facilitates straightforward and secure wiring of individual cables.
ISO 1724 Conformance: Guarantees compatibility with international standards for 7-pin electrical connections, ensuring reliable operation with compliant vehicles and trailers.
Standardized: Conforms to ISO 1724, ensuring broad compatibility with 12N systems.
Durable Materials: Features a robust plastic body and long-lasting brass pins.
Easy Wiring: Equipped with screw terminals for secure and accessible cable connections.
Common Application: Widely used and understood for basic trailer/caravan lighting.
Gasket Sold Separately: Requires an additional purchase (MP99B gasket) for full weather sealing.
12V Only: Not suitable for 24V systems.
Limited Functionality: Primarily for lighting; does not support auxiliary power, charging, or reverse lights (which require 12S or 13-pin systems).
Plastic Construction: While durable, plastic bodies can be less resistant to extreme impacts compared to metal alternatives.

The Maypole MP23B 12N Type 7 Pin Plastic Socket serves as the vital electrical bridge between your towing vehicle and trailer or caravan, exclusively for 12V basic lighting functions. Its design is focused on providing a reliable connection for your indicators, brake lights, taillights, and fog lights, ensuring road safety and legal compliance.
This socket is ideal for:
Small to Medium Trailers: Including utility trailers, boat trailers, and camping trailers that only require basic lighting.
Older Caravans: Many older caravans utilize the 12N system for their main lighting.
General Purpose Towing: Where auxiliary power or advanced functions are not needed.
Secure Wiring: Always ensure all cables are stripped correctly and securely fastened under the screw terminals to prevent loose connections or short circuits.
Regular Inspection: Periodically check the pins for dirt, corrosion, or damage. Clean with a suitable electrical contact cleaner or fine abrasive if necessary.
Proper Sealing: The effectiveness of the socket in outdoor conditions largely depends on the correct installation of the recommended rear gasket (MP99B). This gasket prevents water and dust ingress, which can lead to corrosion and electrical faults.
Correct Plug Mating: Always ensure the vehicle's 7-pin plug is fully inserted and securely latched into the socket to maintain a consistent electrical connection and prevent accidental disconnection during travel.
Prepare Mounting Location: Choose a suitable, secure location on your caravan or trailer for the socket. Ensure adequate space for wiring behind the unit.
Attach Gasket (MP99B): Before mounting, fit the Maypole MP99B rear gasket (sold separately) over the back of the socket. This is crucial for weather resistance.
Mount the Socket: Secure the socket to the chosen surface using appropriate screws or bolts. Ensure it is firmly attached and cannot vibrate loose.
Wire the Terminals: Following a standard 12N wiring diagram (often found in your vehicle or trailer manual), connect the corresponding wires from your trailer's lighting system to the brass screw terminals inside the socket. Each terminal is typically numbered and color-coded. Ensure all connections are tight and secure.
Test Connection: Once wired, connect the trailer to your towing vehicle and test all lighting functions (indicators, brake lights, taillights, fog lights) to confirm correct operation.
Voltage: Designed for 12V electrical systems only.
Type: Exclusively for 12N (Normal) type 7-pin plugs, which handle basic road lighting functions.
ISO Standard: Conforms to ISO 1724, ensuring compatibility with other ISO-compliant 7-pin N-type plugs.
Keep Clean: Regularly clean the internal brass pins and external plastic body with a soft cloth. If pins are visibly dirty or corroded, use a specialized electrical contact cleaner or a very fine wire brush, then apply dielectric grease.
Inspect for Damage: Periodically check the plastic body for cracks or physical damage, and inspect the wiring for fraying or loose connections.
Protect When Not in Use: If the trailer is stored for extended periods, consider using a protective cap over the socket to shield it from environmental elements.
