Al, I used 6mm wire for my set up. Maybe overkill but when talking about braking systems better to be safe than sorry. In terms of the Reece Hitch your better off to
park both car & van on a level surface & then tinker with the angles of the towing head & the links on the bars to get to a point where both car & van would be level as if they were in an unattached scenario. Also remember to have the van & car as close as possible to travelling weight & weight distribution. ie
water tanks full fridge & other equipment packed etc.

12 gauge is 3.31mm2 so 4 mil will do the trick

I used two strands of 6mm for my brake wire just to be sure.
For the hitch go here and get a set of instructions
http://www.haymanreese.com.au/consumer/advice/index.htm
This page has the fitting instructions in a PDF file

Best advice is adjust hitch to correct height using cams then hook it up It should have at least 5 links or it is too tight and to adjust you pivot your towball back.
The reason for this is if you turn too tight and the chain hasnt enough links it can bind and even snap a bar as they move forward and back when turning

I also used 6mm, it goes straight in to the trailer plug with no problems.
In fact, I did thousands of kms with my Track Eagle CT & only ever had the 6mm charge wires in the trailer plug with absolutely no battery problems ever.

Yep 6mm from battery to controller then also down to 7 pin plug and soldered the cable in the pin. Paul

Why solder?

because the screw wouldnt do up properly hence soldering it in.

Most good quality plugs will take 6mm no problem. It's the cheap ones that don't.
I've done hundreds, no problems with the screws.

I was just curious as to why it was soldered.
Following a thread here last week, I asked one of our marine electronics technicians about soldered cable terminals versus crimped.
His opinion is crimped 100%.

Lowest point of Hayman Reese torsion bar should 130mm from ground when tensioned to stop hitting speed humps/kerbs driveways ect

Hi Charlie,
I think this a bit too much of a generalisation. Vehicle hitch and van coupling heights vary over a very wide range and, for example, while the ends of the bars being 130mm from the ground on a Falcon towing an A-liner might result from a proper set-up, it would probably represent a totally incompetent set-up on a raised Landcruiser towing a Bushtracker.
Al, if you read this, please feel free to send me an email and I'll send you a copy of some notes I wrote for a friend on H-R hitch set-up a while ago. We've been on the road for most of the last 6 1/2 years and I think I've got the system sussed out reasonably
well, not from
well-meant hearsay, but from technical sources and industry experts.

Ian
You assume I am generalising with my reply. I have beem caravaning for over fifteen years and 9 of them with HR setups over 3 vans and vehicles. I sell and setup HR hitches to some of my customers. Yuo are correct in saying all the different styles and setups are all individual but HR in thier setup papers say that the min distance is 125mm from ground WHEN WORKING.
As I said 130mm required should have had min before 130mm my mistake.

Hi al
all the other wiring seem ok about the hitch.....when I towed a 16 foot caravan back in the 70's 80's....put the van and car on a level when the van is level the hitch should touch the top of the tow ball, bars should should be used to bring all to a level the main thing is to keep the front of the towing vehicle as close to its normal hight

al,
if your trying to decide 4mm or 6mm - another consideration is which of those wires will physically fit into the plug.
there is no point running a 6mm the length of the vehicle then cutting it down to make it fit into a 4mm size hole at the plug end.
good luck
