How do I connect the two prong end of the 12VDC heat trace cable to a positive and negative line running from my fuse box for my 12v system?

There doesn't seem to be a positive or negative wire just the two bus wires. TIA

It won't be polarized.

Would you be able to expand on this please? It’s my first time doing this, and what I think you mean is that there is not positive or negative end on the heat trace cable, therefore, I can just connect it to either the negative or positive side of my fuse box? Is this correct?

It's just resistive cable, so no positive or negative.
As with all electricals, do a test wiring before fitting.

Use heat restant connectors or crip it.

Why or what is this and for what.
Growing funney plants perhaps.

If its trace heating you also need some other stuff which I presume you have, (switch/thermostat)? If not the trace heating will be a constant drain on your battery

If you’re missing the switch or thermostat, that trace heating will drain your battery constantly.
