EDIT: Updated with new information about where to attach wires
Standard warning: before hooking anything up, make sure the power to the spa is off. Preferably flip the circuit breaker for the circuit supplying the spa. Your spa may plug in, in which case, pulling the plug is also OK. Do not ever work on the spa without the power turned off. The household current can kill you.
I don’t know how much you already know , so I’m going to assume you have no background at all. I apologize in advance if I’m going too basic, I’m not trying to mansplain I’m just trying to answer the question without making assumptions.
With that out of the way, here is what your wire colors mean. The brown wire is the hot wire. In household 110V AC wiring, it is the black wire. The blue wire is the neutral wire, the same as the white wire in household 110V AC. And the green/yellow wire is the ground wire. It is the same as the green or bare wire in household 110V AC.
Here are some videos on how to connect wire to screw terminals. They are shown for electrical outlets for a house, but same idea for any screw terminal. I’m not endorsing these as the best sources, just that they do a good enough job of showing you how to do it
For solid wire: https://youtu.be/q5aEGrnhK88
For stranded wire (wire is many small wire strands bundled together) : https://youtu.be/YyrcL6yLoZ8

And lastly, here are what I believe to be the correct connections based on a matched board being sold on aliexpress and the associated connection schematic.

It sounds like you have screw terminals to hook the heater wires to. If they are on a circuit board , these may be labeled. Written next to them, there may writing spelling out Hot Neutral and Ground. Or abbreviations such as H, N, G or Hot, Neu, Gnd.

Or even more likely there may be no obvious labels but one terminal is silver, another is gold/brass colored, and a third is green. If this is the case, blue connects to silver, brown to brass, and yellow/green to green. Worst case, you can post a photo and it should be easy to tell you exactly what to do.
