Superb build might make the box up. Something to do And possible future install.

Hold off on the D- Box Yax...
I didn't like the 1st one as it had a habit of nipping wires and causing shorts.
MKII was good for mapping the wires, seeing with ease, what went where, but it was too big.
I'll get some pics up of MKIII, much simpler, much smaller! 07 Land Rover Discovery III HSE

Building D-Box MKIII
Best make a start on the build of this little relay box...
So just a quick recap on the very start of this thread, in an effort not to have to many wires all over the car, I opted to run 7-core trailer wire to the roof rack. All the way thru I've made an effort to keep the colour of the wires in order so that when I connect them to the relays and in turn the switches, I don't get confused.
White - Front Lights
Blue - Rear Lights
Green - Right Light
Red - Left Light
Black - Earth
Brown & Yellow - Not used on the roof
First off I got 4x Fused Relays and fitted them with 20Amp fuses.
I then taped them together to make my life a little easier...
First I attatched the power wires (red) to terminal 30, the earth wires (blue) to terminal 85 and cropped them to the same size.
Next I used more 7-core and attached the relevant colours to the relevant relays. (It doesn't actually mater which relay, so long as you join the same colour wire to the same relay)
Lights go to terminal 87 & the switches go to terminal 86.
Also I took the earth (black) from both lots of 7-core and taped them to the original blue earth wires...
From the 7-core marked up for lights, you will have the yellow & brown wire spare, tape them up or cut them off.
The 7-core that heads towards the switches, only the brown is not used. I used the yellow to power the illuminated switches. I used a 2Amp in-line fuse between the main bulk of red power wires and the yellow wire...
I'll leave it here for now... 07 Land Rover Discovery III HSE

Building D-Box MKIII Continued.
For the next part of this build, there's a number of ways you can go... I guess it will really depends on how much space you have in your chosen box. I'm using an outside junction box, I plan for a nice tight fit. I didn't want it crammed like MKI, but I also don't want it all rattling round inside knocking connections off!
We need to join all the positives to each other, and the same with the ground. You could twist all the wires together or copper crimp them... But I've chose to use Wago Lever Connectors.
Unlike crimping them, I can add or remove wires easily... And at this stage, if your not using this type of connector,then you're not ready to bind them together until you have a long wire ready for ground and another with an in- line fuse for the positive.
Because I could only get 5 lever versions, I had to bridge two together for the ground and positive.
But once done, it's a nice looking and simple solution.
Now it's time for a test fit... Make sure you can get all of the wires in place before we get the drill out!
Again, I'll leave it there for now... Not much more to do! 8)07 Land Rover Discovery III HSE

D-Box MKIII - The Finishing Touches.
Four holes need to be drilled into your box. Lights, Switches, Power, Earth.
Then it's just a case of feeding your wires thru the holes. Its at this point, if you're not using the same lever connectors as me and have chose to copper crimp the wires together, your power and earth can be joined.
It's also a good idea to put a zip tie around any wires leaving the box. If there tugged, it'll just give a little extra support and stop connections inside the box being compromised!
Now just feed it all into the box and tuck away the spare wires if you decided not to cut them... They could be handy for illuminating and/or earthing another bank of switches.
Put the lid on and call it good!
All that's left to do now is fit the correct connectors on to the ends of the switch/lights wires and the pos/earth wires.

Well just ordered everything up. We'll both have to wait a while though as most of it is coming from China
Will make sure I do a write up with lots of photos

I'm Glad To Say It's Finished!
Here we have, at long last the final stages of the build.
1st off, the final touches on the D-Box... I was going to use bullet connectors for this, but thanks to Andy Foster and his build, I decided to use actual connectors!
Sometimes you can over look the simplest of ideas... This keeps everything nice, neat and simple. I used an 8 way and a 6 way connector.
Once the connectors were joined to the wires coming from the switches and the lights on the car, I hooked it all up to a booster pack to make sure it all worked before setting everything in place?
Happy that it was all working, I had to decide on a final position for the D-Box... I chose to remove the Alarm Sounder, (Automaticly making the alarm sound thru the Horn instead... Another mod off the list!) free up that space and put it there.
Once it was all tucked away, it was time to put the Aux Battery back in place and hook it all up!
All in, I'm really pleased with the build. I had to go thru two prototypes to get it right, but it was totally worth it.
I hope that you guys and girls have enjoyed seeing it come together, and I hope that it has given some of you inspiration.
All The Best. Jay07 Land Rover Discovery III HSE
