So after some digging around i made this diagram..
so if this looks right all it is, is soldering 4 wires together to accomplish the cable firstpersonview is making right???
after checking all the voltage outputs and inputs i don't see a need for any resistors or anything and i watched firstpersonviews video about 100 times and the cables look straight and i dont see any additional heatshrink on the wires where a resistor would be.. unless im totally missing something here is the diagram i came up with
First off, there's nothing going on in the pre-made cable besides connectors. Voltages all line up, etc. The convenience of the cable is that there are a few connections to make when using an iOSD
1) Between Phantom mainboard to iOSD: vid+ (yellow) and ground (one of the browns)
2) Between Phantom mainboard and Fatshark Tx: power+ (red) and ground (the other brown)
3) Between Phantom iOSD and Fatshark Tx: vid+ (yellow) and ground (black).
Look closely at the cable in this image:

It's kind of a neat trick. All four Phantom mainboard wires run to the iOSD, only two (vid+ and ground) go into the iOSD. The other two (power for the TX) get twisted up with two wires coming OUT of the iOSD. So the bundle going to the Fatshark TX is:
- red (power+ from Phantom)
- brown (power ground from Phantom)
- yellow (vid+ from iOSD)
- balck (vid ground from iOSD).
If you don't have an iOSD, then the image you posted looks right to me. It would be great to find a source for spare camera cables from the Phantom (the red,yellow, 2 brown), or at least the connectors that go into the mainboard. Then I could make up one before I even open the Phantom and keep others around for when I change my mind about my FPV gear and need new connectors.
