There is only one way to make the towing settings work on the rover and when they do, it makes a big difference. The Rover detects a trailer is connected by detecting resistance caused by the trailer lights. Because all modern trailers have led lights, there isn't enough resistance to be detected. I literally tried every device out there to fix this problem including splicing in resistors in my trailer wiring. This is the only device that works: http://www.ledtowconnect.com/p/development-history.html

I like the sound of this but it isn't cheap is it?

Relatively, no. And I think only the Evoque requires LED lighting. The sport should handle good old incandescent lights without issue. Correct me if I'm wrong but the service department used incandescent trailer lights to test and make sure I had a connection.

I really don't mind spending the $$ for added safety and efficiency but is it still necessary in 2017? My dealer seems confidant that it is not but I've learned to trust forum members more.
Thanks!

It enables the real tow menus that you guys want. Things that change once connected:
Backup camera shows path of trailer AND rover
Air suspension adjusts better
Backup sensors are disabled
Flashing trailer icon with turn signal
Transmission shifts MUCH better (single largest improvement I'd say)

I spent hours and hours on fixing this so hopefully I can save you all some time. I've towed 15k+ miles with my 7500lb race trailer and it's a breeze.

Re: Valuable brake controller information

Just wanted to say thank you to 383Vett for providing the wiring diagram.

Picked up my RV yesterday and my Prodigy P2 did not work in my 2016 RRS (with the same plug used in my 2012 RRS). I moved the P2 from my old car to the new car and assumed it would work the same, nope! Land Rover has utilized the same plug (Ford) but has changed all the locations of the wires in the newer Range Rovers. LR dealer was unable to provide any info so a quick search here and I found 383vett's post and wiring diagram which saved the day. And if you weren't sure how to change the wires around in the plug he provided pictures of that as well

Shout out and thank you and another example of how this forum is great.

I know I'm brining back this old post but I also wanted to confirm to others this works on 2016 models.

Sorry to bring back an old thread. But wanted to ask a question about this comment.

Does that mean your 2012 rrs plugged into the 3035 Ford harness without the need to move any wires? You only had to move wires when using it in the newer rrs?

I have a 2012 rrs and just installed the Tekonsha p2. I used the 3035 Ford harness as it came (didn't move wires) . I believe it works as it turns on, I press the button on the right and number 6 comes up, if I press it again it goes 6/1, 6/2 and 6/3.

Then when I pull the trigger, it just says NC (no trailer hooked up yet)

I believe it's working correct? Plugged in properly?

Thanks!

Re: Valuable brake controller information

Took my new 28' Airstream out for it's 1st trip this weekend and had major issues with the Prodigy RF brake controller. Thankfully very helpful and nice full-timers in our two campgrounds were able to help us out - I bet they had a good laugh after we rolled out though. :)

1. Dealer installed the RF brake controller on the tongue of the trailer, and did the initial pairing to the RF handheld with a Ford pickup truck as they know that the Range Rover is not capable of pairing with the RF brake controller.
2. After moving the RF handheld to the Range Rover, it worked well all the way down to the 1st campground, where we unhitched.
3. On the day of departure on the 1st campground, we connected the RF handheld but got a flashing 'NC' which indicated that the handheld had amnesia.
4. We found someone in the campground who had an older pickup truck, but it had an aftermarket 7-way so it was not capable of pairing. We found someone else with a newer truck where we successfully paired and we were on our way to the 2nd stop.
5. Handheld had amnesia as we were leaving the 2nd stop, and I was able to borrow the helpful camphost's truck to pair the handheld again.

Seems like losing power on the brake controller causes things to unpair - anyone else observe this behavior? Our trailer is down in Ultimate Airstream in Portland for a month for some custom work, then off to get solar and lithium installed, so we have a month or so to figure things out... I'm thinking of switching to the wired P3, but not a fan of having the big unit drilled under the dash...

I also want to note that the Curt LED 7-way Adapter DOES NOT WORK, and even if it did, it is poorly constructed. As the 7-way entry point on the Airstream is a very tight fit, and the LED tail lights are a sealed unit, I'm having my solar/lithium installer do the resistor work for me.

The 3035 tekonsha connector for the Prodigy P3 on the 2017 RRS works correctly out of the box. Don't need to move the white and black wires.

Unfortunately, the LED trailer is not picked up by the car. I tried both the curt and etrailer brand LED adapter. Neither worked.

Does anyone know for a fact that the transmission / shifting program is controlled electronically via "knowing" that the trailer is connected?

I installed the 3035-P into my 2018 RR Sport TD6. The pinout locations on the harness in the truck are correct with the adapter harness. It installed and works perfectly.

just an FYI.

I installed Tekonsha P3 and 3035-P harness. I am not getting any power to the brake controller. I do have tow package, and vehicle shows connection to my trailer when I use turn signals. I hooked up the P3 to another vehicle can (LR3) to check if it was defective, and it powers on in the lr3 - but not the Sport. Could it be a fuse issue? Is the wiring any different in the 2014 RRS?

Interesting, I removed the 3035-P harness I got from Amazon looks to have the same wiring configuration as the 3035 in the initial post (or I am misunderstanding). It looks like I need to move some wires around as per the diagram. I was under the impression the 3035-P was good to go, apparently that is not the case. Thank you for this info!
