Bluetooth working, but no WiFi?

Thought I was going to have a completed build today but unfortunately ran into a few issues.

Wifi and BT have been the area I have so far been super uncertain, and haven't found a ton of clarity.

I'm did a Vanilla Mojave install and everything went smoothly, but I don't see an option for wifi. In all honesty I'm not super surprised. I'm using this adapter https://www.amazon.ca/dp/B00THN281U/ref=cm_sw_r_cp_apa_i_VcvqCb1AG2VCW

With the BCM94360CS2 Broadcom chip, and don't really know what I'm doing. Installing the chip was fine. But have no idea what to do with the cables coming off from the antenna, thought they might just be there to amplify the signal to the chip.

As mentioned BT working fine, but there is no WiFi icon or way to configure as far as I can see. The led on the adapter is lit so I'm assuming it's working, although worried about compatibility.

Any help would be greatly appreciated. The Fenvi T-919 isn't an option.
