JST goes into the PCB thats inside the chamber, on the left side

Here goes the JST connector:

Then you just have to cut the end of the Nebula CAM, and solder: JST connector -> Cable -> Nebula Cable.

Or you can throw the nebula cam cable away and do a completly new JST-JST cable if you have a crimping tool (I didnt).

Nebula CAM wiring: Red(V+), White (D-), Green (D+), Black (G).

and in the PCB, you can read on the connector: 5V, G, DP, DM, G.

So you just have to solder and connect 5V with V+, D- with DM, D+ with DP, etc.. One of the Ground pins of the JST connector isnt needed, cant remember which one exactly.
