OBC Upgrade Wiring Question.
 

Just undertaking the OBC upgrade as described in 101 Projects and I have a couple of questions I wondered if anybody could help

I assume the connector into the Cluster where you put the new cables is the Grey one, not the Blue or Green?

Also my car was registered in UK January 2001, so I assume was in factory in 2000. As the cables are connected differently between 2000 and 2001, how do I find out which to use? The VIN decode comes out with 2001 as date.

Many thanks for any help anybody can give me.

Europeans are pretty formal about their Simmer Holiday and I think you can assume that anything built after August 1 is considered the next year model.
