That component is a connector. It appears to have 6 pairs of wires. Each pair of wire is sheathed in each black coloured cable insulator.
Each pair will likely be associated with 1 string. Black wires could possibly be reference, while the red wire is an analog signal that is probably meant to be processed by a dedicated module..... maybe with a low pass filter front end, followed by maybe a pre-amplifier, then into an analog to digital converter. And that is for 1 string. The same kind of thing for the other 5 strings.
If you don't want to cut the connector, you could possibly try to find the counter-part one, so that you can connect your existing connector to it's mating connector..... and then you can have access to the various pairs of wires.
