Very good article, thanks for preparing that. A few additional tips:
A very quick +12V switched supply is fed to the brake lever microswitch.
This can be tapped into easiest by removing the switch to connect the wire (through a hole in the the +ve spade) and re-bolting it back, pre-assembled.
The earth can be connected to any decent bolt that goes in the frame but choose one that is not exposed to much corrosion.
Before assembly, it is worth connecting the grips to a 12volt mains adaptor to check that the heating elements work and to find where they are fitted in the moulding.
The warmest part should face forward on the bike (this also tends to match the recommended 'wiring exit angle' for the LH & RH sides on good grips, at any rate).
Firm-hold hair fixing spray does work well as a grip-glue and gives you some assembly and positioning time before drying.
Still wait at least 12 hours with any gluing, though.
Before starting work, offer the grips and wiring loom up to the bike to get an idea of what is going where, cable routing, pre-assembly required adjustments, etc.
Heat-shrink as many of the connectors as possible.
After assembly, the wiring loom should not be pulled tight during, or foul the action of, turning the bars from lock to lock.
