Aha! Thank you, found it -- well, found the very cheap looking much smaller black equivalent that was in the foam compartment in the spare wheel well (I now have a space saver wheel in there, I had transferred the towing eye and pump-with-gunk setup just in case but didn't notice this bit!). Appreciate your pointing it out
