However, car's user manual suggests connecting to somewhere on the chassis.
This can be a pain, getting a good connection. Any thoughts TIA.

I've always done the former, except where the battery is inaccessible,
then the latter. IMNHO, it makes little or no difference.

Don't think earthing polarity has anything to do with. If you make a spark
near a charging battery you risk igniting the hydrogen. Considerably less
risk with "sealed" batteries admittedly.
