Help needed replacing 3-way switch with occupancy motion sensor
I want to install a motion activated light control at one end of a 3-way switch. Instructions and wiring diagram did not give me much confidence without asking for guidance.
Motion sensor has black, red, yellow/red and ground wires.
3-way switch had 3 black wires attached to the common (black) terminal, another black wire (hot?) attached to the brass terminal above that, and a red wire (load) attached to sole brass terminal located on other side of switch (Can post some pictures once my cell network comes back up!).
Having difficulty determining which is "Traveler A", "Traveler B", etc. as per Leviton's wiring diagram. Any help is appreciated.

If I am looking at the diagram correctly it is drawn for how to wire if the power, a 2-conductor black and white cable, comes in at the box where the regular 3-way is. If that power cable comes in at the box with the sensor switch then the wiring would be different. Which box does it come in at? Was there a third diagram.

The only other diagram on the instruction sheet is for wiring a single pole installation.

First we need to determine which of the three black wires to the common go to the light that will be controlled..
One way to do this is disconnect all three black wires. Using a meter or test light determine which is the power in black. Now connect one of the two remaininf blacks to it. Does the light to be controlled light up? If not try the other black wire. When you find which wire goes to the light to be controlled mark it with red tape or red felt tip marker.
Got to go for now. Will post more instructions later.

I will wait to hear back from you. Thanks!

Ok I will refer to the black wire to the light as black/red.
Do not touch the neutral bundle. Leave as is.
Connect the sensor red wire to the black/red.
Connect the sensor black wire, the common wire from the other 3-way switch, one of the travelers from the other 3-way switch, and the two remaining blacks in the sensor switch box together.
Connect the Sensor yellow/black to the remaining traveler from the other 3-way switch.

- what about the power wire, I don`t think you mentioned it unless you called it something else and I missed it.
I hope my post is clear and I`m not confusing things...Thanks!

I connected the sensor red wire to the black/red, the sensor red/yellow wire to the red traveler, the sensor black wire to the hot black and the other 2 black wires in the sensor box, and then placed a jumper wire on the other 3-way switch as per the installation instructions, and the switch is working nicely.
Does that sound like it makes sense? If yes, then thanks for all the help Ray!
