Does the other one go to the actuator?
I dont know what that means lol
I believe paultownsend was referring to the other hose you had highlighted in your picture coming off the n75 valve and down by the bulkhead. It's basically to control the turbo's wastegate actuator and in response to Nino, yes. You can replace that hose with a length of vacuum hose too, although it is slightly larger, I can't recall exactly but I believe it to be 6mm ID, it then joins to a reducer back to the original 3mm ID hose to the actuator.
