Well g'day Skee Bo, and it would appear nobody answered your questions!

Loose vac lines - do you have Euro headlights with the level adjuster? If so does it work? They may be for that. Without a picture it's hard to tell. Those vac lines will not have anything to do with your door locks - they are on a separate vac system, but if they are slow, you may have a leak in that system.

The ICV is at the front of the engine, up the top just peeking out from under the air box, about the size of a roll-on deoderant bottle. It has an electrical connector on one end (closest to the grille) and a thick rubber hose out the side - quite short. The ICV is silver.

Getting trans fluid out without draining the trans is simple. Stick a very clean hose down the trans dipstick hole and suck it out.

I use oxygen tubing and a 20ml syringe - but I have access to these.

Cheers
