Land Rover Stop Tail Light dual filament bulb nominal 12 volt 21 / 5 watt filaments1412 viewsThis is the Land Rover part number 264590 dual filament bulb, (P21/5), that inserts into the upper two tail lamp receptacles. In the upper one, both filaments function, in the lower one, only the 5 watt tail light filament functions.
I regard it as not a good practice to routinely switch bulbs when the tail light filament, (5 watt), burns out on the lower bulb. The broken filament can jiggle over onto the brake light filament, (21 watt), and short the circuit to ground or something else not predicable.
There are also arguments to say that quality control is better on the Land Rover marketed bulbs than say far east sourced bulbs. Filament construction, and hence resistance can vary and mislead the current sensing circuits monitoring the signal light systems. Also when the bulbs are properly installed, all filaments should be standing vertically and not at any slope.
These are the sort of obscure circumstances that can lead to false trouble messages on the display, dropping to the stops, and subsequent concerns - all over a tail/signal light bulb.
For example, the filament life of both the tail light and the brake light filaments in the P21/5 bulb is significantly less than the USA common 1157 dual filament bulb, (1000/250 vs 5000/1200 hours); brightness in the P21/5 is a bit more, (3cp/35cp vs 3cp/32cp where cp is candle power), but current consumption is oddly less, (0.44a/1.86a vs 0.59a/2.10a where a is amps). It is the quest for efficiency vs maintenance trade off.

4 pin NAS flat connector from NAS small trailer377 viewsThe connector with the three exposed pins is the end that would commonly be located at the trailer hitch end, (front), of a small NAS lightweight trailer that has no electric brakes. This plug would connect into the flat 4 pin connector at the rear of the 3.
Note the order of the pin functions and wire colours: White is ground; the next pin is for tail/marker lights using the Brown wire; the Yellow conductor is for the left turn signal, and the far pin uses the Green conductor for the right turn signal.
There is no separate brake light conductor as NAS spec vehicles most often combine the brake and signal light functions to the same bulb filament rather separate filaments in different bulbs. The LR factory harness resolves that design difference.
Fortunately, the Land Rover NAS assembly pin order for the 4 pin flat plug maintains the above described conventions.

6mm PA12 grade nylon tubing with heat shrink applied 538 viewsShows some of the 6mm air line with heat shrink applied to one end of tubing. Shrink will be applied to the other end once field cut to length. These four tubes, each about 20 ft (6m) long, feed to the rear. Re the front air lines, (not shown), four additional lengths, each about 10 ft (3m) long, are required plus one more 3 metre length for compressor air. The 6mm tubing is a Nylon product specified as PA12. There is also a very similar Transport grade PA11 material, however it seems that PA12 is the more common Transport grade now in use. Also the applicable DIN standard seems to be both DIN 73378 and DIN 74324 for the nylon tubing. The working pressure of the 6mm tubing is about 27 Bar and bursting 82 Bar @ 20C. This is for the 1mm nominal wall thickness material, (4mm ID, 6mm OD).

Exploded Parts view calling up 6R60/80 and 6HP26/28 variations3094 viewsThis single page jpg exploded parts view indicates some commonality between the Ford and ZF versions of the early and later six speed units. Technically this sheet is for the RWD units as there are variations between plain RWD units, 4WD, and AWD. The transmission in the LR3 is called by ZF to be a 6HP26X and by LR in some publications, the 6HP26

NAS 7 Blade Round plus NAS 4 Pin Flat Vehicle end Socket522 viewsThis shows the function of each blade when looking into the connector at the vehicle end for the 7 pin NAS plug. The layout is the pin order for most new North American pickup trucks and the LR3/4.
The colour and gauge of the wires feeding into the back of the plug varies even within manufacturer model lines.
Also detailed is the flat 4 pin layout common on smaller trailers not having electric brakes. This includes most U-Haul rental trailers.

Stop Light Lamp Circuit pdf2460 viewsThis pdf shows the brake light circuit for the NAS LR3.
Note that power for the brake light bulbs can come either thru the brake light switch power feed /contacts plus also from the Hill Decent Control, (HDC), system relay located within the Central Junction Box, (CJB) - yes two separate sources of power for the brake light bulbs. This would tend to explain how a brake light circuit concern shows up as a hill decent fault message; also why lesser vehicles without hill decent braking mechanisms, (HDC), never display this sort problem when a brake light bulb or switch acts up. You never have a problem related to a system that does not exist.
Additional evidence of the relationship of the HDC and the tail light circuit is demonstrated by when the HDC actually acts to slow the 3 down, the brake lights automatically illuminate even if the slowing action was merely retarding the engine speed or shifting to a lower gear, (in other words, no foot on the brake pedal).
There is also a tie in to the Cruise Control and hence a failing brake light switch can affect cruise operation or just create false Cruise Control messages. To further complicate the issue, while there are no messages generated, operation of the radiator electro viscous fan can also be negatively affected by the fouled set of secondary contacts within the brake light switch. This is all because the NC contacts within the brake switch send misleading messages to the ECU.
While the ground wire design is similar to other vehicles, note the grounds for the brake light filament and the reverse light filament are common on each side. That means that if one has a non functioning brake light on one side, the reverse light may not also work or that some problem with the reverse lights could back feed into the brake lights. This situation while unusual, can result when grounds are corroded probably due to swimming in rivers and creeks or just routine driving in a marine environment.

LR 6HP26 transmission oil part number TYK5000501413 viewsThis jpg shows the genuine Land Rover transmission oil, part number TYK500050, for the 6HP26X tranny. The Shell product number is M-1375.4 but you cannot buy the oil retail from Shell. The container size is one litre.
A routine oil change where the pan/filter combo is not changed takes about 3.5 to 4 litres of oil. When the tranny is brand new, a dry fill can take up to 9.5 litres of oil however around 7 litres is more common for when a new pan/filter combo is installed on an already in service transmission.

Transpo Regulator IN6349 Pin Assignment710 viewsThis pdf shows the Land Rover and Ford pin naming for the 3 pins in the receptacle of the Transpo IN6349 regulator that accepts PWM signals. This jpg is as if you are looking into the receptacle located on the alternator.
Also provided are the Transpo pin names that are in common use and that some may be more familiar with plus some comments re testing.
The IN6349 regulator is used in the newer LR part # YLE500390 alternator. For the older YLE500190 alternator, the regulator is a Regitar VRH2005-142 unit that is shaped a bit different than the newer IN6349 regulator. Externally, the main difference is that no shiny fins are visible on the rear of the newer YLE500390 alternator. The pin naming and numbering is the same for both and both alternators are interchangeable.

Air Compressor 70 amp replacement relay1384 viewsThere is a software update, 09 April 2010, LTB00270, for the compressor which reduces the shut down pressure to about 205 psig (14 bar). The update is usually done when changing to a new compressor and also includes replacing the R7 relay in the engine compartment fuse box, 07 DEC 2010 LTB00331.
The newer grey case coloured relay, part # YWB500220, shows to be rated at 70 amps, (the relay, not the compressor), however the previous black case coloured relay also indicates 70 amps.
Both the new and replaced relay show on their wiring diagrams to have a parallel voltage spike resistor, (probably 560 ohms), across the coil terminals, #1 and #2. This means one does not just replace the relay with any four prong 70 amp ISO sized relay that one happens upon.
One presumes the grey relay is either upgraded or just being installed for good measure. The relay is common on Ford Fiesta for the seat heater relay, Ford part number 5M5T 14B 192 EA; also Volvo, part number 30765034. The Tyco part number moulded on the grey body is V23136-J4-X62.
