So I had a good day fettling around in various parts of the car yesterday and managed to get quite a lot done.

As you can see the actuator and cable are both installed. The cable is simply a shorter version with as steel L section in it at the end before it goes into the bulkhead. The fluid reservoir was straight forward and it all works fine except for the cable end in the foot-well now hanging lose and knocking about! [

I also tried installing the throttle pedal components only to find that they wouldn't fit. On closer inspection of the catalogue there is a different lever and bracket for RHD cars with CC (code name M454) so I guess that means another trip to my local Porsche garage. This is not a good thing as a rather tasty looking Cayman S has caught my eye over there and I really I should be doing everything I can to avoid the place as a result. My eye is ALWAYS bigger than my wallet! [

So, whilst I was in the footwell I decided to have a look for a bracket to fit the clutch pedal master switch to. It Looks like this:
The micro-switch looks like this:
The two holes are 3mm so I'll need to get a couple of M3 bolts to put through them and hold them in place on the bracket. I tested the switch with a multimeter to see how it was wired and found that it's depressed position is on. When you let go it turns off. This makes sense as the bracket holds it tight to the clutch pedal thus enabling the CC system to engage at any time and disengage when you put your foot on the clutch. I also found the two unconnected cables that lead to it; one brown and the other brown with a white stripe (this is correct according to the circuit diagram above - thanks once again Donal!). Just got to figure out which one goes onto which connector now! I suppose it doesn't really matter though seeing as it's simply going to ground and it brakes the circuit whichever way it is connected.
The next thing I decided to do was see if I could find the second ECU connector in the passenger foot-well. Safe to say this was where the vast majority of my day was spent as this is no easy task if you don't know where you're looking....which I didn't!
For anyone else looking to do this you will need to take the glove box out of the dash (six screws on the front, just behind the lid, 3 on the lid hinge at the bottom and one by the glove box light will have it out). Be careful of the connectors for the light as you remove, they're pretty delicate! Isn't hindsight a wonderful thing! [
]
It's also a good idea to loosen off the trim directly above the glove box so that when you put it all back together again you can get the rubber strip in-between the glove box and trim in properly.
In behind the glove box you'll find a black box with the front cut out with LOADS of wires! My connector was in here....:
....right at the back! I sliced the cable tie holding the loom and by dislocating my lower arm and hand in several places managed to untangle it out. Incidentally you cannot get the wrong connectors onto the ECU, one has 7 pins, the other 8 and there is a blanking plate on the 7 stopping you putting it on the wrong one.
The other reason for removing the glove box is that you'l need to access the area at the back of the glove box to secure the ECU. There are about 4 studs coming down vertically from the metal work above and it can go on to any 2 of these. A good tip is to use flanged nuts (M5) for the far stud at least; access it impossible so I placed a flanged nut into the correctly sized socket on the end of a socket screwdriver and kind of felt my way up there. You've got no chance any other way!
This shows the ECU (not connected yet!) in position and the two connectors which I have tied up for now. You can also see the studs securing it in place.
It was getting late by that time and I hadn't broken anything yet so I decided to quit whilst ahead and call it a day before anything went wrong! So I put the bits I'd taken off the car back together leaving the unconnected parts in for another day.
I decided to do a little maintenance whilst putting it back together. The glove box light has never worked so whilst it was off I had a quick look....
Turns out the copper connector which also acts like a spring (the curved one) wasn't actually making contact as it springs back so a little bending with pliers and it's all working a treat now.
Not sure when I'm going to get a chance to order the other parts and get them all fitted now (was hoping to have it done for next weekend but sadly not).
One question which I would like to know for those of you that have CC already installed: when the engine is off and the throttle pedal is resting is the lever on the actuator to the left or right...what does the arrow on the actuator signify? Ta...
Exactly the same situation as I am in; self-employed, S2 as an only car, using it to much the miles.
Good to find someone else in the same situation!
(But still can't help with the CC - sorry!)

It's a good situation to be in I reckon! Don't know about you but it makes an impression on clients, is often a talking point and is the best compromise of running cost/fun/character/performance out there!
More to come.....
