Thanks to Corey and Niko for the late night effort and even later night report here.  See the first attachment showing the locations of the installed sensors.  I'm sure Corey will post some informative and entertaining images of the ordeal.

2pm: waiting for ISC to complete. 2:30: All the cables emulated fine so we felt ready to cable up the actual sensors.  But like usual we had a few snags.  330pm: The first sensor went in and out three times as we struggled to orient it as we had foreseen in our fit checks. But we had no cables then and some fasteners were different and that made the difference.  We thought we'd be stuck with just three of the four fasteners in the two corner verticals but then shifted our thinking and disassembled the long hex driver.  The thinner key alone fit into place and then was reassembled with the driver parts and the fastener was driven home.  450: On the V2, we could not get one bolt to start and then realized the hole was already occupied by the beam dump mount screw Corey reported on and moved for us.  Then V2 was complete.  5:30: For V3 and H1 we needed 'inside' help and Corey stepped up with no fear.  After a couple attempts upside down and sideways in the south door nozzle he volunteered to go deeper and shimmied feet first between the isolation stacks putting himself in position where he could hold the assembly in place to fasten up.  After struggles to get the first bolt started, the others went with out trouble; V3 complete.  6pm: Finally H1, one cable fastener is not going into the feedthru.  After a couple attempts, a closer look reveals the one horizontal sensor pulled from storage has a broken bolt in the feedthru.  Corey waits patiently while another senor is retrieved from the staging building.  No broken bolts and a quick and painless mount up in the table---if only we had more horizontals to do. 7p--cold ale time...

I'll report on SNs etc separately.

To Do: * Dress cables down isolation stacks. * Wait for ISC to finish adding/moving elements on Optical Table. * Address other needed cable dressing. * Rebalance table with aux payload.

Edit--In the sensor location depiction attached I got the location of V3 & H1 crossed so I've redlined and reattached the depiction below.
