OK, so the first thing to do, is go to the wiki section of the forum and in there is a link to download the oem service manuals for the car. The 5g manual is for a US model (no-one has access to the UK manual for 5g's unfortunately). It's fine for everything other than it doesn't cover the 4ws system and obviously steering wheel /driver controls etc are on the opposite side of the car.
In there you'll find lots of diagrams showing where things are and step-step instructions.
Have a look and see if that helps but come back and ask anything that isn't clear.
