My FT-991A uses a USB to printer cable. I believe the same is used on the FT-450. Get at least a 6 ft. long (2 meter) length cable so you will have leeway in moving your laptop around (or to reach your desktop, lol) Amazon and flea bay has many...

You need two connections, 1 for CAT rig control and the other for the audio in and out. Yaesu makes the SCU17 unit that plugs into one usb port and works really well, it's what I use on my 450D for both digital and remote rig control/use.

You could DIY it as well for a few bucks less, but much more effort. You need a usb sound card, a usb to serial cable for CAT control and you make the audio cable by cutting up an 3.5mm male to male cable and a 6pin cable.

I would also add, one of the nice things about the SCU17 is it has physical level adjustment knobs on the front for input and output audio.

I had a SignaLink USB for years and, while only marginally cheaper than the SCU-17, it will work across several radios with minimal reconfiguration. It comes with the cables you need, so there's no need to build any cables.

For remote control, pre-made cables are also available.
