    I have recently towed a large trailer with my RRS using that system - controlled by my phone in the cabin.

    My RRS has the OEM wiring loom but I did not connect up the white socket as I did not need it. I have the standard black round 7 pin connector and when I tow my own stuff I use and adaptor to turn it into a standard flat 7 pin.

    The large trailer used the large black round 7 pin socket so plugged straight into the car. The cable on the trailer feeds the Electbrake controller on the trailer and the lights etc. I have a pulse buster for when trailer LEDS are used but the trailer has one inbuilt. The phone synced with the trailer as soon as I put the headlights on - as set up this trailer takes it power for the Electbrake unit from the light cable and takes the brake signal via the brake cable and obviously the bluetooth signal from the phone.

    Worked fine - travelled Canberra to Ballarat and back in two days, so assuming the trailer is wired correctly there is no problem using a Electbrake system with a RRS - the only modification to my trailer wiring is to remove the required tail light circuit to the trailer brakes do not come on when the light are on. I have the rear trailer wiring fuse box so just pull the relent fuse. (RRS/D3 are wired for European trailers which have individual circuits for the tail lights where the Aust system has one circuit for both tail lights - in the Aust system the spare tail light circuit is used for trailer brakes hence on an unmodified system the trailer brakes come on when the headlights come on - there must be a squillion posts on this on the forum).

    So the issues you have are most likely due the leds in the trailer.

    When all else fails, go back to basics.

    So with the multimeter, I was able to test each and every connection - if you are interested, the voltage from the indicators are only approximately 200mV(edited), and the rest are as you expect, around 12v if car is not running and 14.7 if it is.
    Turns out my issue with the left indicator was just a loose/dirty connection. So when that started working I was ecstatic!!

    Also, I removed the blue wire connection in the convertor, so now i only have one tail lamp connection going to the trailer. So its not going to trigger the caravan brakes as soon as the headlights go on.

    Everything works. Besides the above though, I have not changed anything.

    Interestingly, although I still don't have the tralier icon on the dash, it appears that on some level the car does know that I am connected as there is no reverse beeping when the trailer is connected via the elecbrake unit.

    If i remove the elecbrake unit and connect the car directly to the caravan, then it beeps in reverse. So the elecbrakes unit must have some sort of electronic trickery in it that tells the car that, yes, a trailer is connected. Or maybe its just that with it connected there is enough of a load on the wiring to provide the signal to the car. So should i bother with the load resistors?

    On another note, the rear fog lights are connected to the auxiliary circuit (pin 2, also known as the reversing signal on the standard wiring diagrams), how much current can this circuit handle? Enough to run a 3 way fridge on 12v while driving, ie 10A?

    Ok, so after a long trip up to QLD (about 1300km) averaging about 15.6-17.6l/100km there is still no trailer icon.

    The car does know the caravan is connected though - when i reached my brother in laws place, i had to take the caravan down the back to his shed, which was down a steep grass slope - so I put it in grass mode, in low range with the hill descent control on, and a message flashed up saying trailer is connected, off road mode not selected automatically.

    And now the car beeps in reverse - so annoying.

    When we get home to Canberra i will have to put the load resistors on and see if it works better.
