Cruise control light on before start and then disappears

A while ago I retrofitted my 2003 Bxster 2.7, MT with CC and OBC.
OBC was activated and works fine.
CC was activated via Durametric as well and it seemed to work, but only for a short time.

CC activation was done much later... just nowadays.

Initially the green light was lit when ignition on.
After starting the car it will either stay on or turns off with the switch.
It would engage and work fine.

However, at some point on the same day it stopped working.
Cruise control light on before start and then disappears within seconds once the engine is running.
I checked the clutch switch, brake switch, adjusted the brake switch travel... nothing helps.

I cannot get the light to turn on.
Why?

Also, since here.
What is the normal behaviour?

Green light shows up with ignition on, right?
The switch on the stalk will do nothing yet.
Then once the engine is running, depending on the condition of the switch on the stalk, the light will remain lit or goes away. Right?

If lit, you activate the speed control by pushing the stalk forward. Other options, cancel, resume... all typical.
It all worked, but now I get nothing.

Durametric activation was cycled, but no help.

I am confused.

Oh, the B7 fuse is OK.
