No turn single lights on front

Kenworth chassis node

 

What happens with the flashers on? Do the t.s. on the hood work then? Really need a wiring diagram/service data but if you had that you would not be here.
This person in the video has a 2014 T-660.



"once you disconnect the wire harness for the lights it kills the power for all your lights" Can be back probed without disconnecting any harness or connector. Plenty of back probes can be found online. Node just another word for Control Module.
