No this is incorrect.
The laser driver - and +12V go to D9, not the RAMPS power input. You have this labeled fan on your image.
The laser ground wire does not go to the D6, it should go to R9 on the laser driver board. This is covered in the same instructions that you took the image from.
Then you solder a wire to MODE on the laser driver and connect it to D6 as described in the post we linked in the last reply.
