WIRING DIAGRAM FOR 7 PIN EBS ROUND PLUG AND SOCKET

 

Since January 1st 2015 all new trailers (exceptions apply) need to comply to ADR38/04 that specifies they have either Anti-Lock Brakes (ABS) or an Electronic Brake System (EBS) to automatically adjust the brakes. EBS (Electronic Brake System) connectors are used for the electrical connection of the ABS/EBS braking systems between the truck and trailer for both 12V and 24V electrical systems. Whilst ABS has 5 pins, EBS requires two additional contacts (7 total pins) to permit the exchange of data between cab and trailer to optimise the braking effect. The plugs are connected to the sockets with a steel latch to avoid accidental disconnection. The sockets are provided with a plug expulsion system in case the plug is incorrectly connected. Mechanical resistance and watertightness guarantee an efficient and reliable electrical connection.

Upgrade the look and performance of your trailers with our Model 35 and Model 37 Trailer Lamp Kits.

 

The Model 35 range introduces a complete 'Plug and Play' solution for box trailer lighting, making installation easier and quicker. Perfect for DIY. Narva's 'Plug and Play' waterproof connection system utilises over moulded connectors that quickly join the lamps and trailer plug to the main wiring harness. No splicing or joining of wires is required, making connections a tool free operation.

Each kit containes all the necessary lamps to comply to a standard '6 x 4' or '7 x 5' box trailer to Australian Design Regulations (ADR 13/00) for lighting installations. The two most popular trailer plus in Australia are included with each kit giving you the flexibility to use your trailer with multiple vehicles and trailer sockets. Included is 7 Pin Flat and 7 Pin Large Round trailer plugs. Model 35 lamps are also available in lamp only twin blister packs where harness is not required.

Designed from the ground up, the Model 37 trailer lamp has been engineered for use on boat trailers where regular submersion is common (suitable for boat trailers up to 7m). The lamps are protected from water ingress with a two-stage sealing system that incorporates ultrasonic welding and a two-part epoxy glue. This allows the lamps to comply with the stringent IP68 standard. Each lamp is fitted with a waterproof connector and joins effortlessly to the main harness which is also compliant to the IP68 standard. All hardware is made from 316 stainless steel and suitable for marine environments.

Available in twin blister packs and 'Plug and Play' kits, each contains two rear combination lamps (one with in-built licence plate lamp), two red/amber side marker lamps, main harnesses and two popular trailer plugs to suit the most common sockets fitted to vehicles.
