CTEK connections & arrangements?

The e89 battery is in a similar place so shouldn't pose any difficulties.

And then CTEK in the boot ... and cable out to mains via ... ?
In other words, is there a good, non-squashing place for the mains cable to exit the boot?
First off, buy yourself a CTEK extension cable (Amazon, ebay etc). Then take a look below.
The 2 core extension cable (red and black) is just the right length to run from the jump start terminal (big red cover, back of the engine bay slightly right of centre) to the front of the bay just behind the LH headlamp as you look at the pic. You then just need to find a suitable earthing point for the black core (I used a fixing on the suspension turret). Just make sure all connections are clean and free from any contaminant, then put a smear of vaseline or similar over the connectors.
Lightly cable tie the CTEK extension cable to existing runs but keep away from heat sources where possible (helps keep smoke and flame where it belongs, not loose in the engine bay). Only downside is you have to pop the bonnet when connected - but with a bit of ingenuity this could probably be overcome.
I seem to remember the BMW blokey saying connect this way rather than direct to the battery, might even be something in the handbook about it - can't remember. Cars in the showrooms connect like this so the lights can stay on etc for punters to look at without the battery going flat.
This was how I did it anyway. Took about half an hour. Been working fine for 2 years now.
