When I replaced my radio I discovered that there was no fancy connector involved. Just a bunch of crimped butt connectors on the individual wires. But using the old radio and the new radio wiring diagrams - which were conveniently on the radios themselves - it was a simple matter to wire up the new. There are dozens of styles of available connectors but I like these. They are super easy, fast, don’t require any tools except a wire stripper and hold like the dickens. I keep a good supply on hand at all times and use them for a variety of DC wiring tasks.
