Glad you're giving it a go
Marodon I'm sure you'll be able to get it working
Make sure you have esys 3.30, the psdzdata files, obviously the cable, the updated fitting instructions and preferably ISTA/D or ISTA+ If necessary do the research on VO coding. I have a good guide (which I gave to Padraig) which explains it well.
Just take your time with the wiring, it's time consuming taking the various bits of trim off to run the cable and I'd recommend you buy a trim removal kit, mine was this one

The connections to the BDC are fiddly, just make sure you have your best reading glasses to hand if your eyesight is as crap as mine, check and double check you have inserted the wires in the right pins.
The coding is straightforward as long as you follow the guide. There's absolutely no need to pay any of the remote coding people, some who will charge £50 and upwards for what is a 10 minute job.
Feel free to get in touch if you need any help. All I've learnt has been from various forums so happy to see the knowledge passed on.
