Trailer wiring

[bbyer]

I just added a wiring harness to my LR4 . An update is required or your backup sensors will think you are closing in on a wall. $100 for the update .

I presume that Land Rover has resolved the quick flash concern related to LED trailer lights behind an LR4?

If so, it seems odd, (or very Land Rover), that LR would not have factory programmed for auto cancellation of the backup sensors when a trailer is attached.

The fact that an update is apparently available means it could have been programmed in with the factory load. Come to think of it, is it with early LR4's or all LR4's?

For the LR3, there was no required software update to get the backup sensors to shut down as long as the trailer behind appeared to have tungsten trailer light bulbs. I use the word "appeared" as that was why it was necessary to add hardware that would fool the backup circuits.

OR....maybe I could just turn off by backup alarm when I have the trailer connected??

Ok so today I installed the wire harness from Atlantic British, and it was pretty straight forward.
1 thing I will say is anyone that is going to do this.....save yourself some serious time and banged up knuckles and drop the spare before you start, MUCH MUCH easier access to routing the cable over the bumper.

I have not done the Trailer Ball BCM update as I do not have OBDII device and I live in WY a ways from LR dealers or Reputable shops that can help out. So I cannot speak as to if the Trailer Ball BCM update does anything.

I have a 2006 LR3, and just installed the wiring harness with a brake controller and it worked fine, with no issues.

Rover2042 what brake controller did you use and how was the installation?
