Hi. Picking up a new Caravan shortly here in NSW. Caravan has only been fitted with a 7 pin plug. As a break away battery monitor is required in the car here there appears that there is no pin to connect it to.

Should the van be fitted with a 12 pin plug as to allow this connection which appears from the diagrams I have looked at to be pin number 9 ?

I just want the van to come with the right plug .

Thank you.

O.k I think the reason is solved , the tare weight of the van is 1915 kg , less than 2000 kg.

So I can decide to carry only 84 kg of weight to keep it under 2000 kg which is not going to work , or I can put the 400 kg load into the van , OOPS now it's over two ton so I have to have the van modified to a 12 pin plug and wiring to the brake safe battery.

Very smart of the builders .

You can get a very good wireless monitoring system from Hayman Reese, it will work with all types of Break Away device.

I fitted one, works well.

I am fairly sure break away brakes only need to be fitted if the Tare is over 2000kg.
No amount of load will change tare. Check for yourself to be sure.

Thanks for the replies .

It is based on GTM , but given the vans tare is 1915 kg and the regulation is if the GTM exceeds 2000 kg I can only load 75 kg of weight.

GTM , the weight of the trailer standing on it's own wheels , not connected to car , with all items loaded water , luggage , gas in bottles , plates , forks , bedding etc.

So 75 kg is totally impossible , so in this case you must have a break safe connected and a monitor if in NSW.

lets get this straight ...... what matters is what is stamped on the plate ...... not what it weighs empty or laden ...... what the Gross Trailer Mass that is stamped on the compliance plate.

cheers

The manufacturer of your new caravan needs to answer your question. Ask them for the required wiring diagram, which they all should happily provide and follow it.
