Hi all , truck is a 300tdi 90 , so I’m rebuilding the main harness as there were loads of scotch blocks and dodgy tapping ins . I’ve stripped the harness down to its component parts and seeing as it’s here I want to completely delete the dim dip circuit, I have searched and found Dave asked the same question but wanted to check I was doing it rite before snipping away . So first question is what is this connector for and am I safe to remove it ?

there wasn’t anything attached to it and I had a look on LRWorkshop but couldn’t see it, second brown/green trace wire I’m presuming is for the diode on the inner wing and safe to remove,

and lastly the dim dip relay itself, from reading the only wires needed are the blue/red trace which you join together and you can safely remove the others?

was worried about the blue wire here , so if anyone can confirm the above is correct or no you’ll blow yourself up you numpty 😜 I would greatly appreciate it.

cheers Ian

the plain brown comes from a joint off the main light switch & the brown/green goes to the dim dip relay from the resistor. see page 20/32 in http://www.legionlandrover.com/manuales/electrical schemes - defender 300 tdi.pdf upper part of diagram, the dim dip relay is on this page as well.

I don't know what that red 3 pin connector is for, can't see anything like it in the above 300tdi wiring diagrams.

Cheers western , so joining the blue/red wires together and removing everything else is fine , thought that's how it was but wanted to check . I know it's definitely factory but couldn't find it on LR Workshop either .

PaulMc is great on these later looms,  I bet he would know what its for.

Yes just join the 2 blue/red wires to retain the normal dip headlight function.

Yes I will need to speak to him about some connectors at some point , but I think he's closed his shop during lockdown as it's not on eBay . Just a thought , what about for a factory fitted alarm ? Lights flash when it goes off .

Yes I had seen he had closed his ebay pages, but I'm sure he would respond on here or to a PM. 

Sorry I don't know enough about the factory alarm system.

I’ve seen that red connector on mine but can’t for the life of me think where it is. From roughly  on your loom where would it go?

It’s behind the binnacle or by the fuse board I think , there is another connector similar/same for the clock . It’s on the wire from the dim dip relay back to the fuse board, I think can look tomorrow.

Yes I did this mod on my 200 loom. I can't help with the red connector, but the only wire you need to keep is the blue/red, cut and join either side of the relay. The rest of them can go in the bin. I was quite surprised at how much I took out.

Cheers all , yes I was surprised as well Dave it takes out a fair chunk, so thought while it’s on the bench it might as well go and make it less cluttered behind the dash . I can leave the little red plug in for now as it’s after the relay just in case it’s needed .

The other mod I did at the same time was to add relays for the headlights. Those yellow relay holders just clip together, so I got 2 more of them, swapped a few wires around down at the fuse box, and added in a dedicated power feed for each. Probably how LR should have done it originally.

Yes I agree , already got all the bits to do that mod just using the old circuit to switch the relays for the lights . I know Landrover didn’t but is there any need to add a relay for the side lights ? I am and always will use led’s so I’m thinking not .

The wire colours tell you a lot;

I think the red 3-way is fog light plus main beam, so perhaps a warning light or something?

Green/brown is a gauge, possibly an optional one, the wiring diagram will tell you.

Cheers all, @daveturnbull did you also remove the aircon wiring as that’s not much use either ?

And for 100pts does anyone know what the symbol for fuse 19 means looked on line but no joy , think it’s something to do with the aircon as a brown slate wire from that plug loops round through the 5amp fuse back to the plug .

Yes I can imagine , I’ll remove it I think I’m never going to fit air con . Thought it was something to do with the aircon Ralph .

I think that is the "Take That" fuse  https://takethat.com/
