All I can add is that the wiring in the rear loom appears to be in place for them and tucked away as shown below top right.

BTW double check the loom is fixed higher than in my build picture, as I later found the protruding end of the top link bolt was chaffing the loom

Have since fitted shorter bolts.
Colour codes are L/H rear pair black/green & black, R/H rear pair black/blue & black.
Would be interested to hear when and if you fit them. So far just upgraded my front ones to
these.
