Translation:

Ventilation and heating of the interior of a Land Rover Defender depends on the heater fan. This heater fan speed is adjustable by means of a position switch that can run softer fan via resistors.
This rule is also the source of a poor and inefficient working fan making ventilation, heating and demisting of the vehicle is inadequate. Only in the TD4 models from Land Rover is an adaptation came on the stove and fan unit, for all Defender models to TD4 we have devised an electronic control.

This electronic control replaces the existing switch and control resistors and sends the current fan motor directly. This direct control of the fan motor will be adjustable and in many cases have a higher air output. As a result demisting will function better and the interior heater to get a better return so that the vehicle can be quickly heated.

The application of this modification requires some skill and assembly tools, so this modification includes assembly can be purchased in our workshop in Dordrecht.

So does it come with fitting instructions ?

Yes it does - In Dutch!!

I have one on the shelf in the garage. I was hoping for some English instructions, but not had time to find any yet. 2021 Defender 110 X-Dynamic HSE D300 MHEV

What about the cable that operates the flap? Do you just leave it open? 2014 - current ..... 2003 defender td5 90 (my car)

Looks like it says that in the first paragraph.
Disconnect cable and push in completely so air valve(flap?) remains open and is no longer used.

I just received my kit from Landreiziger for the variable fan speed slider control. I installed the switch this afternoon, what an excellent upgrade. Cannot recommend it enough. Increases the fan speed appreciably and the variability of the slide control is just great. The install was super easy and the kit is set up to be simple.

The step by step instructions, which were included, are ok but not great. Still it was rather simple to figure out.

Following the instructions I removed the gauge cluster and undid the existing fan speed switch and pushed the cable all the way in. This is an important step as if it is out, you won't have any airflow.

Next I installed the new slider control switch. Important to note that the instructions were not clear on which way to install it, be sure to put the two wires on the bottom, otherwise your fan speed graphic in the dash will be reversed (ask me how I know).

Click image to enlarge

I ran the wiring loom through the grommet at the bulkhead after spraying a bit of silicone on the opening to ease the pulling of the wires. The wire has a cable tie wrap heat shrinked to the three wire loom for super easy insertion through the mess of wires in the dash. This is a great feature which I will use in the future (one of those why didn't I think of this years ago moments).

The three pronged plug is ready to receive the wires and you just insert them and plug it into the switch.

Click image to enlarge

Next move to the engine bay and run the new wiring loom along the bulkhead to the fan and heater control box. Once done unplug the wires as indicated in the instructions and cut the bullet connector wires as shown below and then add on a crimped spade connector (these were not included in the kit). Connect the wires according to the colour codes indicated on the control unit.

Clean the side of the air box with a good degreaser, I used brake cleaner. Position the new control unit and center punch the four holes for drilling.

Drill the four holes, this can be a challenge if you have LHD with a snorkel.

I chose to tap the holes for the suplied machine screws but they also provide sheet metal screws if you would prefer that. The drill to use is a 3/32 or 2.5mm. The tap was an M3.

Once done, add some thermal paste (not included in my kit as it had to be shipped to me overseas and it is considered "hazardous" by some countries) and screw the new control unit to the heater box.

Click image to enlarge

Last to do is to choose a grounding location on the firewall. Stay away from using a wing ground. I chose the upper wing anchor bolt at the bulkhead.

Click image to enlarge

You are now done! Check out your easy to slide switch and improved airflow, defrosting and heating.

I chose to add a few trim screws to the blank holes left by the removal of the original switch as I just don't like holes on my dash.

This is an excellent mod and although a bit pricey, I cannot recommend it enough. Hope this is useful to some.

Fantastic write up. Very helpful

I've been tempted to buy one myself, and if I ever do, your step by step guide will prove invaluable!

End note to installation:

I have recently been in touch with the vendor ( Martin) and he informs me that the thermal paste was not included in my kit as it has been problematic for overseas shipping. So if you order it and you are in Europe you should get the paste.
