Hi all, just had a weekend that did my head in and caused a few hours of lost sleep last night...

During the week I had a Prodigy brake controller fitted. With the back of the socket filled with resin, I thought the best way to connect the brake control wire was to splice with the existing wire... this is where I went wrong... thinking it would be as easy as opening the loom and splicing onto the BLUE wire.

As I now know, the colour of the wires behind the socket (vehicle side) are "not important" to functionality. What is important is that each pin does what it is meant to in accordance with the Australian Standards. Therefore, if you wire your plug (trailer side) as per the standard and don't try and match the socket (especially if you are having trouble with the trailer wiring as well), you will save yourself a trip to the looney bin and have no issues.

I guess the lesson is: when you wire in a brake controller and run the brake control wire (blue) to the back of the plug, make sure you confirm the colour of the wire that connects to pin 5 in the socket before splicing...

Does anyone know why LR would throw a curveball like this?

Not just LandRover, Many European manufacturers wire in accordance to their own wiring regs...BMW, Volvo, Mercedes, Jaguar(which is the same as LR) wire their plugs this way.
Just remember that most (nearly all) European manufacturers have 2 park light curcuits in the loom(left & right). this is where it causes issues.

Cheers.

p.s. if any help is required just ask. I have wired many Electric brakes to these vehicles.;)
