Do S5, TurboII have a SHIFT INDICATOR LIGHT like S4 do????

 

No.. you mean shift up light right?

If so no.

 

you really dont need one, i promise

here's where you shift:
2500-3000 rpm while the engine is cold or in generaly for economy

6500 rpm (turbo) for fun

 

Ah, ha. Thank you.

I'm looking at a series four C-01 plug and they called it Shift Indicator.

We've a S4 gauge cluster in a S5, and a RL colored wire from thei S5 idiot light is going to the shift indicator light in the gauge cluster. Not a proper thing.
