Having trouble with ABS / Skid Control 2012 Jeep JK

Have a fault in left rear wheel sensor bad, replaced the sensor but it did not clear. I have 7 volts on the left rear sensor, and 10 volts on the right. I might have tweaked the wiring on the left side too much but not sure. Is there a wiring harness for the rear ABS system? Any ideas on what to do next?
 
Some abs/traction control systems wont clear a wss code until after its driven.
The sensor itself is wired straight to the controller. I believe the sensors in yours are digital. that means the only ways to check check them properly would be with a lab scope. if you have a way to read data, you could at least see what the controller sees. Its not easy to test the sensor for voltage due to the fact the controller sends to voltage to turn on the sensor. these can be on a timer.
These type of things I spent a lifetime diagnosing professionally. I can tell you with confidence, the number of factory wiring issues are few. This does not include, something chewing on wires, outside damage or broken connectors due to negligence.

Almost never has it been a controller, 90% of the time its the sensor, hard collision to the wheel area can crack the tone ring, rodents have been known to chew wires. Stereo and alarm installers have caused me more issues than the last few items.
That leaves the fun one, cheap aftermarket replacement parts. This has caused me more misdiagnosis then anything.
Take it for a drive, see if it will clear. If the code is still there post the code and I'll see if I have access to any real diagnostics.
