EDM GT-S Cluster, PWR light VSV?

[Rascal21]

Another day, another gripe!
I want this PWR light (Novelty item, I know) working (Since I have it, and it`s cool):
   

I know which wire it is, #2 Green-Red:
   

I traced it to the engine bay K plug:
   

And according to the wiring diagram it should be like so:
   

Problem is though, I looked at the placement of all stuff in engine bay:
   
   

And I`ve found VSV for T-VIS, 12v power supply Black-Red wire on 14P (G) plug on Junction Box No.4, Ground via #9 pin on ECU 18P (at around 4500rpm).
I`ve found idle VSV that is controlled by Idle-Up Computer.
And I`ve found the secondary A/C idle VSV.

But I cannot find any earthed VSV (K plug) for the PWR lamp...
Any takers?

Now to get one
Case closed!
