Thread: D3 Electric Trailer brake wired-photo

Hi John,
The wiring harness in the vehicle in the photo has a white tag on it. This "IS" the trailer harness side. From the Grey plug that goes back into the vehicle wiring harness & towards the CJB.

The Blue wire to the Socket can be done if you follow the factory wiring harness once you remove the tail light assembly. It can't go into the rear of the socket as it has a hard resin filled section. So i just connect it behind the plugs which leaves about 4-6 inches or original cable.

Cheers

Hi Pete,

That is exactly what I wanted confirmed; thank you.

Thanks also for clarifying the blue wire/brown wire socket connection. I will run with that advice too.

Cheers

Hi Pete,

Sorry to bother you with this issue again!

As you will see from the montage of photos I've taken of the wiring behind the LHS tail light of my 08 RRS, I am a bit confused about which of the 2 green/purple wires I need to cut to fit the diode. Is it the one going to the green connector, or the one to the grey connector?

Also, unlike your D3 photo, you'll also notice the trailer tag is under the car one the cable near the back of the trailer sockets in the chassis cross member. Is it therefore correct that the diode must prevent current feed up the green/purple wire (which ever one it is)? "Up" in this case, means towards the grey or green connectors shown in the photos.

Note that i think there are wires to the grey connector, and 7 to the green connector.

Comments appreciated...

Cheers,
John

Pete,
I realize that you refer (in your response of 11/06/14) to the grey plug (that goes towards the CJ, but since I didn't see a green plug in your photo, I assumed that maybe the RRS might be slightly different ...! Of course, if I'd had any experience with D3's i should know that, but I don't, hence the caution.

I assume the information on this thread as it was started in 2008 applies to the D3 and the equivalent RRS? I have to put in a brake controller and I want to make sure I am not following D4 instructions.

Hey John,
It is still the one in the Grey plug. The green plug from memory is the rear park sensor loom. The wire sizes will be different also & the one in the grey plug will be thicker.

Better being cautious than not.

Cheers

Hi Garry,

Yes, this is the thread for the D3/RRS, not the D4.

Thanks Pete.
