Now I just have to get to an Indy Shop/Dealer to activate both through the computer.

I took my time for fear of breaking something and this took two days, no breaks. If I had to do it again probably 4-5hrs. My garage temperature was around 5 to 6 C so plastic parts aren't as pliable.
When removing the instrument cluster all the documentation tells you to lift straight up after removing the 2 screws behind the telephone speaker and the hazard flasher. They don't mention that there are 5 plastic tabs helping to hold the instrument cluster to the dash. Likewise with the Trim Ring around the steering column and the dash, it is secured on top with 2 screws and under the steering column there are 2 plastic tabs, lift straight straight up.

The condensed wire plan is;
2003-4 Boxster Cruise:
Plug C (Grey) on the Instrument Cluster Pin 17 - Stalk Connector Pin 1
Plug C (Grey) on the Instrument Cluster Pin 4 - Stalk Connector Pin 3
Plug C (Grey) on the Instrument Cluster Pin 1 - Stalk Connector Pin 4
Fuse B7 - Stalk Connector Pin 2
2003-4 Boxster OBC:
Plug C (Grey) on the Instrument Cluster Pin 23 - Stalk Connector Pin 2
Plug C (Grey) on the Instrument Cluster Pin 22 - Stalk Connector Pin 3
Plug C (Grey) on the Instrument Cluster Pin 21 - Stalk Connector Pin 4
Plug C (Grey) on the Instrument Cluster Pin 24 - Stalk Connector Pin 5
Earth (ground) - Stalk Connector Pin 1

so let me get this straight.
If one is to install the 4-stalk, some wires are "doubled", in other words, connected to same pins from the stalk, but different on the gray one (C plug).
Pin 1 is ground and goes to Pin 17
Pin 2 goes to Pin 23 and Fuse B7
Pin 3 goes to Pin 22 and Pin 4
Pin 4 goes to Pin 1 and 21
Pin 5 goes to Pin 24

Is that right?

Base 2003.
I hope to get clarification soon as I am in the middle of the project...
