Picked the sensor off the blue car as the silver one is still being decontaminated and was not in the yard until next week.
There was a steel crash bar behind the front valence held on by 4 bolts with the sensor (item 2, 3, 8) hiding behind and clipped to it; there was only wiring in conduit, no air pipes, leading towards the offside headlight area. Could not see hose aspirator (item 6) or sunbeam sensor (item 1).
I cut the wiring where it joins a larger bunch and unclipped it, it's in the back of the car right now and is light & small enough to post. Might go back on Wednesday to see silver car if I finish early enough.
