Thread: D4 Electric Trailer Brake Wiring

Here is how I mounted the Teckonsha P3 in the D4. Followed sniegy's instructions like many others for the wiring. As it was first new car ever at the time (12 months ago now) was not keen to drill holes and would not have gone down well with SWMBO anyway. So with hacksaw, vice hammer and pop rivet gun, managed to modify the supplied bracket and fit so it could be removed without trace. After a while you realise your are never going to do that anyway but its a thought when you first have it. Also attached is the wiring diagram I made up to show someone else how to wire one, and also how I mounted a 12 pin plug where the landrover white one goes, as van was set up for 12 pin so it has camera etc in one plug.
The P3 has been good towing 3500Kg van and see further down the post for how to use its in built diagnostics. I just got a spare to carry with me, $135 on ebay. The original came with resetting circuit breaker thrown in but was not in the $135 deal.

Regards
Gerry

After I saw What-The's quote for $3,000.00 to $4,000.00 for dealer fit brake controller I had a little panic.
Austral fitted brake controller, Traxide Dual Battery Kit and supplied Tow Tongue for Mitchell Hitch for half that amount. Blood Pressure is now back to normal.

P3 Controller definately needs Boost, I push the Boost Button but nothing happens, am I missing something?

$800 for redarc unit including installation by Melbourne City Landrover Port Melbourne. Adjustment knob on right hand side of steering column behind steering wheel. Knob was a little loose so
wound single strand of a rubber band around shaft and now all good.
No stuffing around, took less than 2 hours to do.

Question on the purchase of the Redarc unit.

I can get the basic unit which seems to comprise just the module and controller and no other hardware for $164. The other kit has the same module and controller but also includes other hardware including cable to run to the rear of the car for $234.

So on the D3/RRS do I need the full kit or just the basic version?

Thanks

Garry

Garry,
I havent seen the cable that it comes with so i cant comment. But the loom that will need to be made for the vehicle will be specific for the vehicle.
The loom that is recommended from LR will require 4 wires from the controller to the rear loadspace. But some people have done there own thing.
If you need a hand let me know.
Personally i would just buy the EBRH version (Electric Brake Remote Head)
EB Series Trailer Brake Controller | Redarc Electronics

& make your own loom.

Garry, what did you end up doing about a brake controller. I'm thinking of putting a Redarc remote hear unit into the D3 I recently bought. I am incapable of doing the install myself, so can you suggest someone in Canberra who I could trust to do a good job of it? I also want to have an Anderson plug fitted at the same time...

I got the Redarc but have not installed it as yet. I will do that myself as it is a very simple process using the instructions supplied and the instructions supplied here. The biggest problem is where to mount the remote contoller.

My brother has one fitted to his Hilux and it works Ok - he also is an electronics engineer and indicated that the fuse on the main wire from the battery should have one that automatically resets itself - the logic being that if the fuse blows at a crucial moment the brakes on the trailer cannot be used but with the fuse that resets itself at least you should have power again very shortly - of course if the short that caused the fuse to blow in the first case is a major deal then it will not help. Checked out these special fuses today - about

As who to use in Canberra - no idea but I would print out the instructions put up on AULRO and give it to your installer.
