A friend and I started converting a multi adapter (see attachment 1.jpeg) directly to USB. Unfortunately this isn't as straightforward as we thought (see attachment 2.jpeg and 3.jpeg). We can't find out anywhere what wires would hypothetically be data, power, or anything else.
We have all the tools (voltage meter, soldering gun, etc), but we don't have a schematic or even an idea. We're also worried trial and error with the meter might short something out.
Any ideas?
