OBC Hack isn't working

I just finished the hack and only have partial functionality!
Two of the wires allow me to scroll back or forth through the basic information, i.e., outside temp, fuel mileage, average speed and so on. But the other two wires don't do anything, hence, I can't bring up the OBC menu to check or configure any of the features.
I enabled the OBC using the Durametric cable and software.
Before I go and start checking for faulty connections, am I missing anything here? Do I not understand how the OBC works, or did not fully activate it using the Durametric?

TIA

Actually, I just drove the car for the first time after the hack and all four wires are performing their basic function, i.e., scroll up, scroll down, reset and speed gong.

However, I just can't turn on Display A as referenced in the Owners Manual! What is with that? Can people with the 4th stalk do this? I can think of the following possibilities:

1) The factory wiring for the OBC is more involved than the hack, hence, the hack provides limited functionality.

2) The 4th stalk is more that a simple SPQT (single pole quadruple throw) switch. In other word, it does more than just short one of 4 signal wires to ground. If so, does anyone have the switching diagram for it?

3) What I got is all there is to the OBC and the factory illustrations are no applicable.

Any and all input would be appreciated.

TIA
