I placed my order with Aquamist this afternoon, adding an additional tank adaptor and a High Pressure inline filter. Now I have to wait for the parts to arrive from the UK, and they have a few weeks lead time for manufacture as well.
While I'm waiting, I'm going to order up some of the BMS wiring to try and avoid tapping my original harness. I'm also going to order some carbon fibre braid, some fabric tape, and some of the ribbed plastic cable and pipe wrap that BMW uses all over the car.
I also thought it might be worth posting the following installation diagram for anyone reading this thread:
