Thread: D4 Electric Trailer Brake Wiring

No not yet but I hope you are right, cheers

Not sure what the professionals use, but when I originally put my controller in and used those blue crimp things that attach a second wire to the existing wire 2 of the three failed intermittently as they did not bite into the wire properly. I then got rid of them and soldered the joins and no more issues. So check where the join for the pick up of the brake light happens.

Thanks for the ideas, have not been able to find the fault myself, so car goes back to dealer this week. Will post an update as things progress.

Will be buying a Disco 4 in the next month after missing our Disco 3 for the last 4 years. I have a Tekonsha Prodigy P3 brake controller which I want to transfer from the Pajero to the Disco.

Any (polite) suggestions where I should locate it to minimise holes in dash etc while retaining ease of access. I saw one clever installation in the thread...but are there any other recommendations?

Cheers,
Scott

"scotchloks" auto electricians worst nightmare. Made some one rich initially & keeps auto sparkys in business.

Just a quick note - the problem with my loss of trailer brakes turned out to be a faulty relay in the Disco - quick to fix, but here's hoping it doesn't fail again.....

Hi swordfish,
Which relay failed?

No idea which relay it was. Mrs Swordfish took the disco back to the dealer and brought it home without bothering to enquire where the fault was.....
