Speed Limiter Switch install.......
ok, got the easy part done... thanks to Mike, once again !! 
coding / programming still needs to be done, and will wait for Steve in mid-August to work his DAS magik !
Keep in mind, this is for a 2003 CL203 C320 Sport Coupé. Part # used is: A008 545 27 24. As BenzModz said, there are 3 generations of the switch, so ensure yours is compatible with your car model & year before installing.
in the meantime, here are the steps & pics, in usual Saprissa format:
preliminary:
a) disconnect ground cable on battery
b) ensure front wheels are in straight-ahead position
Part I - Un-Install:
{1} remove air-bag housing by unscrewing 2 screws from behind. Unplug all wiring to air-bag.
{2} remove steering wheel; loosen center retaining bolt.
{3} loosen bolt (2) of steering column module (N80)
{4} remove steering column module (N80) complete with combination switches and clock-spring contact (A45)
{4a} secure clock-spring contact (A45) against twisting using pin (5) in order to prevent damage.
{4b} the pin (5) is included in the clock-spring contact (A45) repair kit, or check w/ Steve for availability if ordering the Speed Limiter Assembly through him.
{4c} the recess for the pin (5) is at approx 4 o'clock (3).
{4d} remove steering column module (N80) from steering column. Pull out from underneath completely.
{5} unscrew bolts (4) just enough to be able to remove the clock-spring contact (A45).
{6} carefully lever off the clock-spring contact (A45) all the way around the sides.
{7} remove clock-spring contact (A45). The position of the steering angle sensor & clock-spring contact (A45) must not be changed since they are adjusted in relation to one another.
{8} remove 3 stalk covers (see 3 pics below) on steering column cover (2)
{9} detach connector of Cruise Control (CC) switch from the electronic ignition/starter switch.
{10} unscrew torx bolt (1) that holds CC switch (S40)
{11} take CC switch (S40) out of steering column cover (2).
Part II - Install & put back together:
{12} install CC/SL switch in reverse order. Attach connector & screw bolt back on.
{13} if no Voice Recognition (VR/VA/VC) stalk is present. Use plug cap from original CC switch to cover.
{14} replace clock-spring contact (A45) / tighten bolts (4).
{15} replace steering column module (N80) into steering column.
{16} tighten bolt (2) of steering column module (N80).
{17} properly re-align & replace steering wheel. Tighten center retaining bolt.
{18} replace air-bag housing. Re-connect all plugs, securing all screws.
{19} reconnect battery & make electrical system operational
{20} perform basic Speed Limiter programming (DAS & IC).
{21} carry out operational check.

Well, Steve coded the instrument cluster for this feature, but it still isn't working. My gut tells me that it is something else that I'm overlooking.
The main problem is that as far as I can tell from reading everything I can about cruise control with or without the limiter, it seems to be related to country coding. In other words, there is only a code for cruise control, and the limiter is related to which country the car is coded for.
Sunman has sucessfully gotten this feature to work in his C class, but swears that it was only in the cluster that coding was carried out. Steve remembered that he also has DTR as well, so maybe there is a connection there somehow.
I'm going to try coding in DTR in a couple of different places on my car, and see if that changes anything.

Steve mentioned something about "Engine Management" and DTR, and that would enable my Speed Limiter function. It was a little over my head, as I still don't quite understand all the different electronic modules and what they do in the car.
I'll be doing DISTRONIC sometime next year probably, so I guess I'll just wait til then.

Carlos,
It all goes back to the networking. All of the various modules in the car have jobs to do, however some only read in switches but another module actually has to do the work, so it sends a message over the network to the one who does do the work. In the case of the speed limiter, the engine management is the one who actually regulates the speed, by cruise control or limiter. So, the steering column module is sending out the switch positions of the cruise control switch, the instrument cluster should be sending out the chosen limit, but if the engine management isn't listening to those messages.....then nothing happens.
For your car, being an 03, it may be possible to code in DTR without a lot of effort. For 04 and above, that doggone SCN coding comes in, which just complicates things. I would have to have Steve change the data card for my car, and when that is done, I would have to request a SCN code and then carry it out. Worth a try, I have to talk to Steve.
This one isn't over by a long shot!!!

tell me about it....
I guess the good thing, is that the DTR icon shows up on my MFD, as well as the text word: "LIMIT", when I first insert the key.
I take it that's a good sign, that my car is at least compatible and the IC is able to send the message. I'm pretty sure my '03 might need SCN Coding and Data Card changes too ! We'll see. Thanks for the info as usual !!
