LR2 Trailer wiring kit help!!! - Land Rover Forums

Hello everyone,

My first Rover and first post with this trailer nightmare.
No one can seem to figure out why the wiring kit# LR003108G
Does not seem to work with my 2008 LR2 HSE.

Man it has been driving me nuts!!!

It all seems pretty simple plug the harness in to the 3 ports on the module and the ground. But I still get nothing at the trailer plug except 3 volts to each positive pole.
The Local dealer even went over all of my work and said that they activated the module and see nothing wrong.

The guys over at Atlantic British are great though they've sent me a new kit and I still can't get it to work. I still get nothing from the trailer harness no brake lights no turn signals no lights what so ever.
I did buy a trailer test plug and it flashes all three positive terminals repeatedly. Probably because they are LED's and it doesn't like that.
My trailer is not an led trailer so that shouldn't be the problem.

I would lean towards the trailer being the problem but its a couple weeks old and friends have already borrowed it with their fords with no problems.

Is there anything special that you need to do to activate a trailer module with the LR2?
also the kit came with 2x15 amp fuses and 1x40 amp fuse but I can only find a location for a single 15 amp fuse and the one 40 amp fuse so maybe I'm missing the location for the second 15 amp fuse?

I really appreciate any help because this is driving me insane! I've been over and over the truck and I can't find any problems.

Aren't the directions easy to read and easy to understand. Not, pain in the but but did you check the fuse location underneath the rear hatch where the spare tire is.

Yeah the instructions remind me of Ikea's furniture instructions.
I did check the rear fuse box but FA9 and FA11 are the only ones that look like a trailer icon. I did put something in FB5 just to test since it appears to have contacts in that location.
There are mini fuses under the passengers side fuse box and nothing that looks like a trailer in the engine compartment either.
But I still have one extra blue 15 amp fuse left over after the install.
I'm wondering if it's an in line fuse somewhere?

The owners manual talks about a Trailer direction indicator on the dash.
I do not see it come on at any time.
For a working trailer hitch install does it illuminate at any point?
when you start the truck or have the trailer plugged in?
I'm just wondering if the dealer did not properly activate my module.

Solved!!!

Looks like it was a bad module from the first hitch kit.
Atlantic British was great sending another one for free.
And so were THE GREAT BRITAINS of Willow Grove PA who worked on it 3 times for free.

Here's a pic of the Hidden Hitch on the LR2 in case anyone is thinking of going aftermarket.
I like the extra weight I can pull and for $150 you can't beat the price

Oliver, what did you do with the plastic cover that the OEM hitch installs under (and that Land Rover has to saw a hole through for installation)?

oliver1071 · #7 07-28-2010, 07:14 AM

I didn't have to do any cutting with the hidden hitch it loops over the fascia.
I was surprised how perfectly it fits.

Thanks, I'm going to order one today.

Looks real nice, very clean.

So it cost you around $500? 360 for OEM wiring kit and $150 for the hitch? Did the dealer charge you to activate the towing module?

Etrailer.com has a wiring fit kit for $60. Anyone used it? Would it still have to get activated at a dealer?

LR gets picky with their electronics...it may void warranty.

Thanks!

It came out to $495 total.
The wiring kit I picked up for $295 I found it at http://www.bputah.com/LR2/Land_Rover...g_Harness.html
But still purchased it at Atlantic British since the have a price match guarantee.
it was $50 for the activation and $150 for the hitch.

I preferred the factory harness and module since it will actually turn off your reverse sensors and tell you if any of your trailer lights are out.
I'm sure it does other things as well with the traction control.

I pulled my trailer before getting the module straightened out and those back up sensors are annoying all you hear is the constant tone when you're backing up since the trailer is so close.
I'd make sure that the after-market kits disable the sensors when you're in reverse before buying one.
