Tuffwing and Pixhawk 4 Mini Setup Help

Hey all,

I am trying to integrate a camera into my aircraft with a Pixhawk 4 Mini but am having some issues. I had this setup previously working with a Pixhawk 2 Cube - so I was wondering if someone with a similar system could help me out. I have loaded CHDK on the camera and am using a Tuffwing cable. The instructions that I am currently using can be found below.

Hey guys! Just wanted to ping this once again to see if anyone was running a similar setup. If anyone can point me in any direction - that would be very helpful! At this point I am very lost.
