I damaged my left rear Speed Sensor on my 2014 while replacing the hub. I had to pull off the knuckle to replace the dust cover. Did that all today, all back together and drives well now. However, I still have to replace the old sensor. I cannot find where the other end of the wire terminates. Back seat pulled and about to go to pulling out the trunk carpet. If anyone has access to the routing, it would be very helpful.

Answering my own question, there is no need to remove the rear seat to replace a rear speed sensor. The connection goes through a grommet in the inner fender into the trunk on the very side. I just removed the side carpet enough to pull it down and attach the sensor. All is good, except I'll not understand why Lexus chose to make such a custom speed sensor assembly instead of just attaching it at the sensor location. $300 for a speed sensor rubbed me wrong, though with all the brackets and wiring, I understand why it costs a lot to make.

Thanks for the update/info. I replaced the front hubs and have yet to do the rears.

Just don't listen to those who say "ignore the rear speed sensor" or any other nonsense. When you break the axle loose, the speed sensor and dust cover come loose and it takes care and caution to get the slot properly aligned. For sure, don't use a zip gun on the axle nut, unless you stop before it is seated and check periodically. Having to take the entire knuckle off, and pay $300 for a new sensor was not what I had in mind when I decided to change out the hubs lol.
