As
@DoomMeister said, those two are only about Power (ground side) and the signal for camera pitch (tilt). They are not related to snapping a picture/starting video. If the camera powers up and responds to tilt when you move the slider, the wire location is good to go.
The video control (pictures/video) are sent directly to the camera via 5.6GHz WIFI signal. So, we need to figure out why the camera is not responding.
The first is to look at the SD card. An SD card that is bad or is not adequate for the resolution you have selected could be the issue. To check this, try a different SD card and:
Ensure the card is a U3 rating (the number 3 inside a "U")
Format the card in FAT32 and use a small card (32G max. Recommend 16G or smaller).
Ensure video settings are no higher than 1920 x 1080F50 (not 4K).
Ensure Photo Format is set to JPG (not DNG)
Ensure Image Format is set to "Natural" or "Gorgeous" (Not RAW)
These are maybe not the greatest settings for photography, but we aren't trying to take great pictures right now. We just want to know if the SD card is the issue.
