Chances of success. F10 HBA Stalk onto normal SZL cluster?

I have no high beam assistant switch. I have a broken SZL with the high beam switch and I have taken the high beam switch stalk off quite easily from the broken unit.

What are my chances of it working if I put it on the non-HBA SZL?

Would I need to code / flash SZL?

Ideas?

Well I tried it. The answer is no, a auto high beam stalk doesn't work on a non auto high beam SZL. I even tried to VO code (with 5AC added) the SZL and also flash it after the high beam stalk was fitted. No luck. Both buttons just cycle the computer.

Eventually I took the PCB from the broken SZL (coil was broken) and put it in my SZL with good clock spring coil. E-sys showed no CAFD! (donor car unknown). So I flashed the new SZL, and all is good. CAFD now visible.

Finally reset the airbag warning with e-sys transmitter and now I have fully functional 5AC auto high beam including the stalk ! Very happy.

Whatever happens with SZL, never let it be turned when off the car, it is a coil, not a slip ring and turning will destroy it for sure!
