Last few days I spent some time here and there to make a little progress. Brake line from rear left to rear right is done. It wasn't as bad as I feared with everything in place. Just slowly wiggle it out and in (well, I could have ripped it out, but wanted to practice the install process).
With the hard line in place, I put a new brake hose on and mounted the Boxster S caliper. Basically the same thing as I had, but better looking and allowing for a wider disc later on.
Next up, the ABS sensor wiring (along with pad wear sensor). Took the old wires out of the wheel well and put the new ones in. Now I need to swap the few pins in the right locations and tidy it all up again. It is a bit of a mess now:
Small tip for anyone that needs to replace this cable: the metal retaining clip of the connector block in the wheel well can be removed easily and makes it sooooo much easier to get it through the hole in the chassis...
