The analog output from the 30-0334 is preferred over the serial. In either case, you would need to add the associated pins to the connector.
The serial output of the 30-0334, as shipped, is compatible with the old 30-4100. So, it is slow, and low resolution. If you send me the gauge for re-FLASH, I can upgrade the serial to be 5x faster with a full extra digit of resolution.
I would use the analog output. It has more resolution and better response times than even the upgraded serial connection. Unlike most widebands, it does not suffer from the dreaded ground voltage offset errors, due to its built-in differential compensation circuitry. Because of the, remember to connect the WB analog- pin to the scanner's ground.
The connectors and pins are available from digikey.com

I would order a few extra of each, as they are usually cheaper than the shipping costs. And, it prevents the need to hack up a perfectly good connector/harness that comes with the WB
