That looks like a complicated way of putting a fuse in!

Pah, boomslingitinthebin more like
First time round I just wired in a pair of relays per light and the second time around I fitted whole new relay boxes and made a proper job of it.
The under bonnet fuse boxes are fed direct from the second alternator circuit and fitted new ceramic H4 connectors and it's been golden.
Only had to do the regular wiring of individual relays into the box to make it all work using a common feed to the fuses and a common earth but that was all.
Relay wired as so.

Thank you both Neily and Dieseldog. Very helpful!
Is it 100% that TD5s have no relay for the headlights? Ive read conflicting information!
Even though today was not a full success I did end up solving the issue I set out to correct. Random loss of headlights which I thought to be a bad earth or bad switching (hence the boomslang) turned out to be a loose connection on the highbeam stalk. Refitted and all is good.

Other than the fuse set up, which confused me, I don't see how or why the boomslang won't work. It just needs a positive and negative connection to the battery and then one of your headlight connectors plugged in to the socket on the boomslang harness to trigger the boomslang relays.

The boomslang would have me fit the fuse in the battery box which isnt ideal for me as I have bucket seats, so moved it to be closer to the relays and be housed in the engine bay instead.
I dont know what it wont work either. All I did was cut the ring terminals off the earths each side and extend them through the conduit direct to the battery as you did.
Connected up male H4 on the passenger side and nothing. Relays click but 0v at the H4 and zero headlights (sidelights work fine). Remove the boomslang and headlights work fine.
Reading your thread is what made me buy it, seemed to straight forward but alas not the case it seems.

I wonder if it's a carped relay then?
Non what so ever! I'm no auto-electrician and that's all I had

Very odd.
One thing I did notice is one relay had 5 pins and on had 4. The 5 pin relay only had 4 connections wired in though

The 5 pin is used to swap power.
Sure it's not used in this loom.
Looked at your earlier photo & it's not wired.
You can use a 5 pin in a 4 pin set up & all will work.

No Defender had relays in the headlight circuits, I've read a lot of threads which muddy the waters but they were never fitted from the factory or there would never have been an aftermarket loom created and people could have bought the whole lighting loom genuine from LR or at least copied it in full for aftermarket reproduction.
It's all well and good for people to post non answers but they were never fitted and the switch gear never changed, why? Because the switch gear never failed inside the warranty period in sufficient scale for there to be any factory upgrades.

Only relays in my 85 loom were hi beam/fog light inhibiters. (Stoped for lights & high beam st same time)
Switch melted so replaced this.
& boomslanged the lights
Later looms had dim running lights(pink relay)
TD5 to posh for me so never looked.

This will be a simple issue - either:
1. Duff relay in the boomslang
2. Poor crimp terminal connection in the boomslang
3. Incorrect terminal wiring in the boomslang
Just need systematically checking for continuity, and checking the relays for functions.
Start methodically at one end and check everything for continuity etc

& you can do the above without putting loom back on the motor.
Just need 12v feeds/earths

Also it worth getting yourself some appropriate coloured small reels of auto cable - or you are going to end up with a total mish mash of colours and Future trouble shooting of anything will be a mare.
Cutting corners/bodgery etc is not a good idea imo
