My W124 3 litre Turbo Diesel - Modernised.
Here's one of their library photos: Mercedes 124 & 126[pp_gal169]/2/
I also ordered some fluorescent paint with a harness & 2 UV diodes, fitted at top part of the cluster:
Needles lighting kit - 2x UV diode, Fluorescent Paint

The description above's OK, but could use some improvement...
Here's some notes / tips:
(1). It's best to fill the tank to the brim before beginning, as the best way to refit the fuel pointer accurately is to power it up - by refitting the large round connector. At the same time you can also refit the oil pressure gauge's pointer - at 3 (I'll go there if only the round connector is fitted).
(2). Only the following pointer needles need removing to fit (Use two small spoons to gently prize them off - it's pretty easy): Fuel Level, Water Temp, Oil Pressure, Clock. I masked the black centres off with selo-tape (It's all they had here and I forgot to bring masking tape with my selected tools for this job).
(3). If you try to clean the inside of the perspex glass, don't use cotton buds - as little pieces of cotton woll can get caught in places & is a pain to remove afterwards!
(4). The Moman kit is supposed to come with a "multiplier" for connectors. I couldn't find mine - but anyways a neater solution is to spice the wires together with solder and shrink wrap and have only one connector going to the inverter.
(5). For the UV lights (To make the needles glow red at night) at the top of the cluster - I obtained power by soldering to one of the brass (earth_ connectors at the back of the temp gauge and obtained 12V from the connector for the clock (Ah bugger!!.... Only just realised this'll make the UV LEDS always stay on... I'll have to get another 12V aux feed...A job to do tommorow... :o).
Careful when drilling holes with this - as it's easy to go through the plastic then have the drill bit hit the clear plastic facia. Having a short drill bit helps.
I took a couple of my daughter's sticky foil stickers and put them on the top of the UV LED's to help reflect their light back at the needles.
Used plastic glue (Dries in about an hour) to hold these LED's in place and also to attach wires to the top of the cluster.
(6). I obtained power for the inverter directly from the circuit board inside the cluster which gives varying voltage to the inverter (Confirm with a multimeter to know which terminal to solder to. It's easy to blow the inverter if the polarities are wrong!).
(7). I only cut away one area to feed wires through, as shown in picture below, then used small cable ties to secure the cables both inside the cluster and outside.
(8). Don't forget to remove the original illumination light bulbs from the cluster. You won't need those now the faces are lit with electro-luminescence.

From http://www.moman.eu I got Design 2,\ which closest matches the original design, incl. same rev counter & speedometer ranges as the 300DT.
