Not to belittle your efforts but there really is no need whatsoever to go to those lengths to make the -ve lead reach.

First of all, forget any talk of an "official" negative connection.

The neg Battery post is connected directly to the car body, so the entire car is effectively the negative Battery post. Any* nut, screw, bolt or bracket that is clean and unpainted (very important) and has a good connection to the body will do the job. That is literally any nut, screw, bolt or bracket that has a good connection with the metalwork, whether that be at the front, back, top or bottom of the car.

* Just beware that some screws will be terminated in moulded plastic brackets/fitments that may not be immediately obvious, so they're no good for this purpose; neither are shock absorber top bolts, in general.

In the photo below the yellow arrows point to suitable places to connect the black lead to - but with the caveat that I don't have an LBX and it's much easier to be there looking into the engine bay than looking at a photo. So don't shoot the messenger if I have one or two out of place

Good point…. But the lead on my booster would probably have reached only one of those bolts indicated and I wanted to be safe rather than sorry. Did it just for my own piece of mind really.

On my NX I use a bolt on the suspension turret and that is nice and close to the positive point under the fuse cover.  I use it for my smart charger when I go away on holiday of anything over a week which is pretty much all the time.

I used a meter on various bolts and they all returned the same reading as the 'official' negative point which is on the opposite side to the fuse box where the positive point is.
