radio wiring harness

[Audifan]

Can the whole radio wiring harness be uninstalled from the car without cutting the wires apart? Here is a old post of mine that has a couple of pictures that I asked about and MikkiJayne said the connector is for the radio. The last time I was looking at the radio wiring harness there is a lot more wires for the radio then what this connector has. My car had some sort of aftermarket radio add on that was wired to the harness and some of the wires were taken out at one of the connectors. If I can find the whole radio wiring harness that hasn't been modified and can be taken out without cutting any of the wires would be awesome and make it way easier for me to just unplug my wiring harness and plug in the replacement harness then trying to fix mine.
