The odd thing is that each 3 pin JST has 4 wires going to them.
In the new pics I can see a bit better from the different angles.
I see the female JST (the one with holes for contacts) with a brown, white, and yellow wire from the cable.
I see the male JST (the one with pins for contacts) with a red, blue, and green wire from the cable. There may also be a black wire; I can't tell for sure. If there is, then that's 7 total wires from the cable itself that I can see.
There is a loop of thicker red wire going from one JST to the other, but that's irrelevant since it doesn't go to the device and it's button; it's not a 4th wire.
How many total wires do you have coming out of the actual cable (regardless of where they go)? Not including the thicker red wire, which doesn't come from the cable.
Since the loop of wire probably goes from one JST to the other to connect a common signal (5v, most likely), then there are only 5 wires from teh cable to the JST itself, meaning that two of the wires are "spare", and probably loose inside the JST heatshrink. My guess is that both of these are in the same JST heatshrink, and thus are in the connector with 5 total wires in it (the loop, plus four others).
If there was never any heatshrink on the cable itself, or if there was but the "loose" wires weren't tucked into it, then they are probably just tucked into the heatshrink of the JSTs (which is not how they were on my old Grinfineons from a few years back; those were a loop of wire tucked back into the main cable itself, for the unconnected reversing wire pair I needed to use for my trike).
If they are, then a very gentle tug on each of the wires within the JST heatshrink will reveal exactly which wires are crimped into it's contacts, and which, if any, are not. That's all it took for me to pull them out on the Grinfineon cable.
The only shrink wrap I haven't removed are the ones cover the JST connectors, but I was going to try avoiding that, since at that point I'd need to disassemble the JSTs in order to get everything re-shrink wrapped. There are definitely no additional wires in the main cable though.
FWIW, if there's no unused wires in the cable (if they are all crimped to pins in the JSTs), then it makes no difference what is in the JSTs, and no need to remove their heatshrink, because they won't get you back up into the device and it's button.
(unless the JSTs are miswired; you can test this with a multimeter, or connecting it to the CA and testing the functions of each control on the device)
