Am sure it's been covered but how easy is the box to fit ( for an incompetent moron like myself )
It is incredibly easy. There is a plug on the left of the common rail for the injection system, and a plug on the air filter housing for the turbo boost sensor. The wiring loom for the box has 2 ends on it. With the 2 aforementioned plugs undone, one end of each part of the loom plugs into the original VW plugs and the other end plugs into the VW sockets. It is a 2 minute job, maybe 5 mins, depending on how much thought and effort you put into redirecting the wiring loom so you don't need to cable tie it to existing looms. Just pop your bonnet, wait 5 mins to ensure the ECU is powered down (in reality, if you hang around the car after locking up, you will hear the electrics click off after around 90 seconds, 5 mins is an assurance that everything is off). You then pull the engine cover off, it is just held frictionally with 4 or 5 pegs, and do the unplugging and plugging.
The plugs themselves have locking tabs, you just need to hold these in while pulling the plug off its socket, for both sockets.
I will post a pic or 2 of the plugged in system later for you. All the plugs are easily accessible, like VW set it up for tuning!
