I didn't strip it out from my car so no pictures. But bought a loom from our sponsor, similar to below library photo. It arrived with all the plastic guides, clips, trunking, fuses, relays etc - even the yaw module.
As for why, I had a random thought it would be useful to have a spare supply of plugs, optical cable etc and A8Parts accepted my offer. If you need a plug Del I'm only down the road
