I think they're around 22-26AWG, same as the original pink/blue wires, however the pink/blue wires may be solid copper core, while the wires I'm using are stranded aluminum.

Now I'm worried they might catch fire/melt/burn. What's your opinion on this? Should I get thicker gauge wires and redo the whole thing?

That feed is fused by the DOME fuse. As long as your wires are sized appropriately for that FUSE you will be fine.
