While waiting I've got to find a better solution to using these fine wires from the sensors and pendant into the terminal blocks.

Maybe bootlace ferrules? Effective at stopping stray strands bridging between channels. 

(And some of the crimpers are fun - there is a little video of a 6-segment one here, though the 4-segment ones work better in cage clamps, I feel.
