I think I replaced mine with 8mm countersunk Allen screws, the hex is much more reliable than a Phillips or pozi head.

The 300tdi disco had a transducer which has a much smaller square drive than the speedo cable, the gear has to be changed to fit a cable.

I have been trying to obtain the brackets for the electrical connectors and fuse box for a 300tdi bulkhead, finally DDS have come back to me to say they will supply them, all ghe other companies either didn't reply or wouldn't supply.

I put a block between the chassis rails and wedge it in to spread the rails slightly. If you have a Porta power then that would be ideal.

The older ones were a full bucket, the later ones were a half bucket, supposedly able to swap the bulb without having to remove everything.

I made supplementary looms for headlights, fog lights and horn, used fused relays and fused the main feed with the connection at the alternator, the relays are mounted behind the headlight support panel, the wiring is fully plugged in so can easily be removed to put it back to factory.

I have fitted the 1.3 to mine with the 4.6 auto, as I found the 1.2 too high and the 1.4 a little low. I haven't had it on the road yet but had done plenty of kms with the other ratios before I made the decision. I am running 285/65/18 which are around 32"

I have a 1.2 behind the R380 in my 300tdi but managed to get the 1.4 box with it when I purchased it, so will be refitting that but changing the R380 5th gear to the V8 discovery gears for higher overdrive 5th.

The driven gear and its housing should come out of the transfer box reasonably easily by levering it up with a screwdriver in the groove just below the cable clip, if it hasn't seized in the transfer box.

Is the end of the drive gear engaging on the new speedo cable, the cable may not be entering or it may have rounded off inside. With the cable fitted to the drive can you turn the other end?

Factory fit is AMR4247 as you said, 100A, I replaced mine with the 120A one from the p38 RR AMR2938. Mine is Denso.

The wiring diagram shows the headlamp flash feed is brown with a purple trace and fuse 3 in the engine bay fuse box, 30amps.

You do realize that a Defender doesn't have one full loom, it is made up of sections, the main loom being the bulkhead loom, then the chassis loom for the rear, the engine loom, and on some models separate front wing looms. https://www.lrworkshop.com/diagrams/land-rover-defender-body-electrics/batteries-harnesses You may find some places having old stock like thexmod.com or Hobson Brothers, I think they are Hobson industries now, otherwise Autosparks make just about any of them to suit. I have just fitted 300tdi looms to my early v8110, but had to make my own engine loom, the rest were from Autosparks, I got mine made to match my 300tdi so both my 110s have the same basic wiring.
