1. Yes

2. I think the actuator is the rod that comes down from the round thing on the left hand side of the first image.

3. I think the one in the middle (of the 1st photo) would be better - in the first photo the bottom side of the turbo is on the left.

I've never tried this myself, but presumably the cleaner needs to go into the exhaust side of the turbo as that's the bit that gets full of carbon and sticks, not the inlet side. I think the way the Innotec stuff is usually put in is by unbolting the exhaust downpipe from the turbo and squirting the cleaner up into the turbo from below?
