Thread: D3 Electric Trailer brake wired-photo

Sorry to revive this thread but I had a Land Rover specialist mechanic install my TowPro and I've noticed that he spliced the Red wire to the Green/Purple wire coming from the 7.5A Fuse and not to the Green/Purple wire coming from the Grey plug as in the original picture/instruction in this thread. He also didn't use a diode. Will that make a difference?

Thanks Sneigy. This has been a bit of a challenge as my wiring seems to be all over the shop. I've just pulled the LH tail light off (previous owner upgraded to D4 lights) and found that the brown wire has been cut and spliced to the tail light feed (red/black wire) for the rear light unit and the black and blue wires have been cut which means the feed from my EBC unit wasn't going anywhere. I will now be running a blue wire direct to the plug.



I'm not sure if this has been posted before but I found this page very useful:

13 Pin European trailer plugs

Very helpful. Used these instructions for my RRS. Took under 2 hours to complete. Thanks again

G'day,

I've finished installing my tow pro. I put the control knob half way up the U shaped surround in the dash. I ran 2 6mm lines from the aux battery, I stripped the system from my Patrol. 1 wire is for the tow pro, which is in the right rear quarter panel and I ran the other for an anderson plug.

Now I've finished the install I've noticed the indicators flickering, which I've bought some resistors in order to emulate incandescent globes.

The reverse lights on the trailer also activate with the rear fog lights rather than the reverse lights. Is there an easy fix for this?

I've also left the anderson plug run in the right rear quarter for the moment as I discovered the white LR trailer plug has some sort of power function. What is the function? I've got 2x100amp hour batteries in the trailer which charge directly from an anderson plug while we're on the road. Is there an east adaption to get power from the white plug? What is this plug all about?

Cheers,

Salty.

I've just finished a sucessful install of a tow pro elite to my D3. I followed the directions in this and the D4 thread and it all worked first time. I've simultaneously (partially) installed the traxide auxillary battery system as well but haven't completed the job yet.

I placed the cpu for the system inside the drivers side dash cavity against the inside wall with industrial double sided tape. The control knob looks pretty neat below the vent. The black control panel below would be preferable but it has a circuit board/module that covers the space behind the blank spot in the right upper corner.

Thanks again to the contributors of this community.

Is this right ???

So I took power straight from the battery via a 30amp auto circuit breaker. I earthed in the passenger compartment near to the unit mounting (under steering wheel console area), picked up the brake from the rear as you've indicated, and fed back the trigger as you've indicated. The diode would seem around the wrong way in your diagram.
For the front to rear run I used a heavy gauge wire for the brake feed and a lighter wire for the brake signal.
