I'll make it simple, still to add to my findings of All wiring at rear door.

Left side rear light:
White/Light Brown...Brake.
White/Dark Brown...Fog Light + Tail Light.
Black/Green............Earth for Tail, Brake, Flasher and Reverse.
White/Dark Green...Flasher.
White/Light Green...Reverse.
White/Yellow...........Fog Light Earth (switched to power light).

Right side rear light:
White/Light Brown...Brake.
White/Dark Brown...Flasher.
White/Light Green...Reverse.
White/Yellow..........Fog Earth (switched to power up).
White/Orange.........Tail Light + Fog.
Black.....................Earth for Tail, Brake, Flasher, Reverse.

Checked Right side wires Flasher and Tail, colours differ from Left side but ok.

I'm fitting a relay, Ryder Smart Logic but some people don't bother. Still to feed power wire to battery.

 

This is for a 2003 Grand Voyager LTD 2.5CRD.

 

Managed to run Battery feed wire below carpet and sound deadening felt alongside original wires and exit it into engine compartment via rubber bung that is obviously the left hand drive steering wheel shaft hole.
Here's the resultant picture behind panel at back door.

 

I'll store this information since I think I'm going to add a tow bar to my V'ger* sooner or later

Yes just let me know if you need info...I haven't tried the wiring on my trailor yet but might get it done today. As per the Voyager wiring at rear lights the Fog and Tail lamps are supplied on same wire but Fog is earthed separately, so may require another relay to energise its earth wire.

 

Hi!
Anybody wiring rear foglights yet. Just noticed this problem when chancing socket 7 pin to 13 pin.
Relay maybe or two but how i connect them that i have 12v feed to trailer foglight..?

 

On a 13 pin socket, pin 2 is + for fog lights and pin 3 is the earth.

 

yes, i know what pin in socket belongs to rearfog. maybe i dont make my self clear.
So question is where from car do you get that 12v to pin 2 in socket
Voyager rear foglight is always connect to 12v (feed is coming same to rear light and rearfoglight) and earth is the thing here, dont figure it out yet. maybe something to do with lightswitch and bcm...
have to check wiring diagram of car..

just asking if anybody do this before me and have solution

 

Well in that case I would use the power to the fog lights on the car to switch a permanent positive through a relay to pin 2.

 

i'll have to check also can i use rearfoglight lamp power (in lightswitch) for relay remote power. and just install another relay (put one to feed 12 current when light is on).
Found same problems with that in all over internet and people are just not wiring rear fog on these "export" voyagers
I'd like to do it properly since i'm start to do this job
