IP67-Rated 1m Gooseneck Trailer Connector with 7-Pin Large Round Plug Built Tough for Aussie Towing Conditions

Product Overview

The LED Autolamps 5C81B is a 1-metre trailer connector cable that links a gooseneck trailer lamp assembly to the tow vehicle via a 7-pin large round plug. Designed as part of the LED Autolamps small harness system, it provides the vehicle-end connection point for the gooseneck wiring setup with a fully rated IP67 seal meaning it's protected against both dust ingress and temporary water immersion, well beyond the demands of typical road use.

Constructed with tinned copper wiring for long-term corrosion resistance and terminated with a 7-pin large round plug (the heavy-duty round-shell format found on many older Australian tow vehicles and some commercial and agricultural rigs), the 5C81B is a straightforward, no-compromise connector backed by LED Autolamps' 5-year warranty.

Features & Benefits

  • IP67 rated — fully sealed against dust and protected against temporary immersion up to 1 metre; handles road spray, creek crossings, and boat ramp conditions without degrading the connection
  • 7-pin large round plug — suits vehicles and trailers fitted with the large round socket format; distinct from the 7-pin flat plug common on most modern passenger vehicles and utes
  • 1 metre cable length — provides enough reach between the gooseneck lamp system and the vehicle socket without excess slack
  • Tinned copper wiring — corrosion-resistant conductors maintain reliable conductivity over time in the salt, moisture, and heat typical of Australian trailer use
  • Part of the LED Autolamps small harness system — designed to integrate cleanly with the broader LED Autolamps gooseneck trailer wiring range
  • 5-year warranty — LED Autolamps' standard warranty coverage on this connector

Frequently Asked Questions

What is the difference between a 7-pin large round and a 7-pin flat plug?

The 7-pin large round uses a circular housing with a locking ring, commonly found on older Australian tow vehicles, agricultural machinery, and some commercial rigs. The 7-pin flat is the most common modern format on passenger vehicles and utes. This connector suits the large round format only.

Does this cable connect to the vehicle or the trailer lamp?

It connects the gooseneck trailer lamp wiring to the tow vehicle — the 7-pin large round plug inserts into the vehicle's trailer socket, while the other end ties into the LED Autolamps gooseneck harness.

What does IP67 mean for a trailer connector?

IP67 means the connector is fully sealed against dust (rated 6) and can withstand temporary immersion in water up to 1 metre deep (rated 7) — making it suitable for boat ramp use, creek crossings, and heavy road spray without compromising the connection.

What is the LED Autolamps small harness system?

It's LED Autolamps' modular trailer wiring range for smaller trailer setups. The 5C81B is the vehicle-end connector in that system, designed to work alongside other compatible LED Autolamps gooseneck wiring components such as the 5C550C cable.

Is a 1 metre cable long enough for most setups?

For typical gooseneck lamp configurations the 1 metre length provides sufficient reach between the trailer socket and the lamp harness connection point. If additional length is needed, other LED Autolamps extension cables may be available.
