Im watching this with interest... Im from the UK so know nothing of these types of controllers!
However, I think I will shortly be looking for a unit that could tow/stop a camper trailer (in the future) but more importantly needs to be suited to a loaded 4 horse float.
So, is weight of trailer an issue for these devices or are they all capable of working on any trailer?
Also, my 110 has the large 7 pin UK style electrical socket, will this need to be changed to one of the flat style that seem to be more common over here?
Sorry for the hi-jack!

No need to change the socket. You can get the large 7 pin plug from Supacheap. Also if fitting a brake controller all you need to do is the following.
In the socket there are 2 feeds for left and right tail lights (pin5 and pin ???). You just join these 2 feeds into a single feed which leaves you pin 5 free. Then use pin 5 for the wire to the electric brakes on the trailer. This wire comes from the actual brake controller and determines how much force has been applied to the brakes. Most Aussi plugs are wired this way.

Thanks Ivan. From your description above there is only 1 wire that goes from the controller to the trailer brakes / trailer mounted system, presumably the system is grounded via the ball and hitch?
Also, (apologies if this is a stupid question) the horse float that we would be towing is not ours - are all electric trailer brakes compatible with all controllers or do I need to find out what system the trailer has on it before choosing a controller?
Thx

Hi Jon.
The trailer is earthed through the white wire in the plug, the coupling makes a very poor earth.
Have a look here for the Australian standard wiring for all the different plugs.
I assume you have a large round 7 pin

It this helps

I'm on my 2nd tekonsha unit in 11 years and 250,000km of towing![]()
Also, make sure the white earth wire is of at least the same gauge as the brake wire. From memory the brake controllers can deliver up to 40 amps, so an 18 gauge earth wire isn't going to cut the mustard.
It would certainly be an eye opener to be under heavy brakes with four horses behind you, then have no trailer brakes at all because the earth wire has become a fusible link.
Speaking of a 4 horse float, what will be the gross weight of the trailer fully loaded ? I am not sure on the exact numbers, but above a certain GTM you must have brakes on All axles. And there is another weight figure above which, you must have a breakaway system that will stop the trailer within a certain distance And hold the trailer still for a defined minimum period of time on a slope.
What I am really trying to get at is towing a 4 horse float is not something to be taken lightly (no pun intended) and you really need to understand the legalities and physics.
