Supercharger Bypass (boost actuator) pinout, L494 SVR

Hello guys!

I am sorry for intruding your forum, but I am getting myself 2018 SVR Supercharger for putting into my 2001 GS Lexus. Big obstacle is bypass valve.
It got electronic one, and I would very much like a pinout, to see if I can find a way to control it

There's nothing about that online, and diagrams are super hard to find (Lexus is not much better, lol)

So, the part name is LR087235, referred as "Boost Actuator"
As far as I am aware- not unique to SVR, but rather widely used across supercharged Jags/LR's

Huge thanks in advance!

Not sure to understand the question
What do you mean by alternative?
