I purchased a Benewake TF03-180 Lidar and was working on connecting it. The Arducopter documentation at https://ardupilot.org/copter/docs/common-benewake-tf02-lidar.html shows serial port 4 connected to the green and white wires. The document from Benewake for the TF03 shows UART on the brown and yellow wires. I wondered which one to go with. I hooked it up to the o-scope and sure enough there is serial data on the yellow and nothing on either green or white. I don’t know if Benewake changed something or not but maybe it should be pointed out in the documentation.

Hi, don’t know if it’s an option for you, but you might want to try to use a pc with a USB-TTL / FTDI cable to validate.
According to Benewake the green and white are CAN.

Read the manual to fix the error, This operation manual covers the product operation introduction and common
problem solutions, but it is really hard to cover all the problems you maybe meet.
So if you have any further questions or problems, please feel free to consult our
technical support service. Explosionweb solutions fix the errors to read the manual, I hope you get help from this pdf -https://acroname.com/sites/default/files/assets/tf03_product_manual_v0.4_en.pdf
The error is in the arducopter documentation, not the Benewake manual. I have no problem that needs help, I was just pointing out that the arducopter document may cause other people issues if they are trying to follow the wiring diagram shown.
