High Beam power for LED Bar

[Marque_c]

Gents (and or Ladies)

I am trying to wire in a LED light bar on my D3 but for the life of me I cannot find somewhere in the high beam circuit to draw my power from.

There is that much stuffed in under my bonnet with all the other accessories already fitted that I have no idea where to even start looking. The harness/relay kit I have been provided just needs a power supply to draw from as everything else is pre-wired, including the on/off switch, so I just need a feed out of the High Beam relay if someone can let me know where it is exactly in the D3...

Thanks

Mark

Back of the Headlight. In the plug itself.
From memory Blue/Black R/H or Blue/Slate L/H headlight.
This is where i picked up my high beam switch wire from & many other customers.

Thanks Sniegy, was a bit perplexed with the wiring around the HID Ballasts, but your advice solved the problem... I am now all hooked and ready to BBQ wildlife at 100 paces with my 288W LED Bar!!

hi Mark, so if I understood correctly there is also a switch for the light bar that goes on the dash somewhere? so that it only comes on with full beam if the switch is on as well? where did you put the switch?
thanks

You will need a relay. 12v from high beam cct to trigger relay and 12v from battery positive terminal which is what you are switching to the led bar.

You can put a switch in series with the high beam to the relay. High be works normally then but keeps the led bar off.

The wiring harness that came with the LED Bar had one relay pre-wired into it, and also had the switch pre-wired into it as well. This setup allowed only for the the LED bar to be switched individually not with the High Beam. This is why I was chasing the switch wire from the high beam.

As PeterOz said it needed another relay installed to allow switching with the High Beam.

Thanks, may I ask which brand it was? I presume they don't all come with a wiring harness

[Marque_c]

Correct... Mine was a 240W Bar from KORR Lighting. I wouldn't recommend them though.

First they sent me a 120W bar with a harness, not the 240W I ordered, then they said (despite me confirming that it was a complete kit and nothing else was required at the time of purchase) I wasn't supposed to receive the wiring harness with it but that I could keep it because of their error in sending the wrong bar.

Then when they sent right bar they sent the wrong mounts for it.

All up from time of order to actually being able to complete the install was 3 months...

That's surprising. We've bought some Korr lights and been very happy with them.

Sent from my D1 using overweight hamsters.

[Marque_c]

I am happy with the light bar... just not the service provided by the company. They just seemed to have no idea what they were doing!!

[PeterOZ]

Where did you mount it? Any pics of the set up ?

Fitted a 40" Hella E series bar ( rigid industries) across the front of my pioneer tray and it works a beauty!! Used a IPF switch on the dash as it was way smarter looking then the one it came with and matched the existing IPF switch for the Hid spotties. Really happy with it and great quality fittings. ( pg 32 show us your disco) ended up blacking the bonnet due to reflection but not fussed about that as it looks kinda different

Just looking at adding my spotties to my D3. How does this work for the relay trigger? There's a constant 12v at the blue/slate lh side headlight on mine

[shanegtr]

Actually scrub my above comment. I was checking with the plug unplugged from the light. Plugged it in and working as expected

Hi Mark, this diagram should help you and as Sniegy posted, the high beam wire on the passenger side is Blue with a "SLATE" ( grey ) trace.

You can find this wire in the loom at the plug that connects to your passenger side headlight assembly.

NOTE it is a very easy and simple task to remove the headlight assembly to get access to the loom.

Run a wire from the BLUE/SLATE high beam wire, into the cab.

Fit a standard ON/OFF switch and then run another wire out to one side of the coil on your relay.

It's all there in the diagram.

NOTE the YELLOW wire coming off the other side of the switch is not require, but if you fit an ON/OFF/ON type switch, you can wire the switch as shown and you can then turn the driving lights on without having any other lights on.

Good for setting up a campsite at night because your headlight only work with the ignition ON.

Hi Tim.
I understand the standard wiring for a switch/relay.
A question about the yellow wire as Ive never seen a wiring diagram like it before.The yellow wire supplies 12V to trip the relay,correct???,so this 12V must be from a permanently live supply,correct????
A use I can see is on aux reversing LED lamps,using the 3 way switch they could be switched either by selecting reverse or manually as you suggest for setting up camp etc.
Cheers

Correct!

[jonesy63]

One slight correction to that diagram... instead of running negative from driving lights to battery, it should go to an earth stud on the body.

[drivesafe]

Also correct, and very good point.

Its an old diagram, so when I get some time I will update it.

Thanks Jonesy

Hi Tim, I used your dwg and picked off high beam wiring from the lhs.
Mine looks like this
.

[shanegtr]

That looks very neat:thumbsup:

[LandyAndy]

Looks factory Harry,well done.

Mine looks like this
That is very neat. And stealth. Took me a few seconds to see it too.

Would be good to see a few photos of the actual installation and how it was done.
cheers
