The wire gauge size of the link is not nearly as important as the material- - - -it's not regular copper wire. The whole idea of a fuse link is to protect the wire harness downstream, so only a short section burns out. Fusible link wire melts at a lot lower temperature than copper, so the wire gauge size does not have much relationship to its melting point. I've tried to solder fuse wire occasionally, and it's almost impossible to do- - - -the wire has only a slightly higher melting point than lead/tin solder.

Here's a chart listing fuse link sizes and corresponding current capacities:

Circuit Hypalon Link Type MAXI Fuse Rating Circuit Wire
Alternator Feed (R6) 12 gauge (black) 160 amp (2x80 in parallel) 8 gauge (BK)
Radiator Fan (C26) 20 gauge (orange) 40 amp 14 gauge (GY)
Ignition Feed (J10) 18 gauge (grey) 50 amp 12 gauge (PK/BK*)
Ignition Feed (J1) 20 gauge (orange) 40 amp 12 gauge (RD)
ECU/ASD Feed (J1) 22 gauge (white) 30 amp 12 gauge (PK)
Direct Battery Feed (L1) 18 gauge (grey) 50 amp 12 gauge (RD/WT*)
Heated Rear Window (C13) 18 gauge (grey) 40 amp 12 gauge (BK/RD*)
Hazard Flasher (A3) 20 gauge (orange) 20 amp 14 gauge (PK)
