## Long description

The Prolech 13-pin plastic trailer socket 4838# provides a compact electrical interface between a towing vehicle and a trailer. Designed as a 13‑pole connector in a durable plastic housing, it supports standard lighting circuits and additional auxiliary connections required for modern trailers. The connector is intended for fixed mounting on vehicles, vans or trailers to enable reliable transmission of tail lights, brake lights, indicators and power supply lines during towing.
Advantages
The plastic construction ensures resistance to corrosion and reduces weight compared with metal housings while maintaining mechanical protection for contacts. The 13‑pin layout supports both basic lighting functions and extra circuits for reverse lights, fog lamps, and 12 V auxiliary power, allowing greater compatibility with a variety of trailer electrical systems. The compact form factor and standardized pin arrangement simplify installation and wiring integration into existing towbar electrical setups.
Suitable for
Connecting car or van electrical systems to trailers for towing
Trailers requiring lighting, brake and indicator circuits plus auxiliary power
Replacement of worn or damaged 13‑pole sockets on vehicles and trailers
Use on agricultural trailers, small caravans and utility trailers
Key specifications
Connector type: 13‑pole trailer socket
Housing material: plastic for corrosion resistance
Functions supported: tail lights, brake lights, indicators, fog lights, reverse light, 12 V auxiliary power
Mounting: fixed vehicle or trailer mounting (panel or bracket installation)
Contact protection: sealed plastic body to limit exposure to moisture and dirt
How to use
Mount the socket securely to the vehicle or trailer mounting point using the designated screw holes or bracket. Connect each wire according to the standard 13‑pin wiring scheme, matching functions such as left/right indicators, tail lights, brake lights, reverse light, and auxiliary 12 V feed. Ensure all connections are tightened and protected with appropriate insulation or connectors. After wiring, test each function with the trailer attached or by using a test lamp to confirm correct operation of lights and auxiliary circuits before towing.
Usage recommendations
For reliable performance, inspect contacts periodically for corrosion and ensure the plastic housing and sealing surfaces remain intact. Use proper cable cross‑sections and quality crimp or solder connections when wiring. If operating in harsh environments, consider additional protective measures such as dielectric grease on contacts and a weatherproof cover when the socket is not in use.
