Re: power and ground connections for AC and cooling fan
2.0 sq mm is a fusible link that will protect a 10g wire (its a 14g link). I have all my main power wires protected with their own fusible link 4 sizes smaller (as is recommended on the MAD Electrical site). These all connect to 1 of 2 insulated studs (CN-1). One is on the firewall and has the alternator charging wire, main dash power wire, a/c system power, battery charging wire and the remote sensing wire from my alternator. The other is on the radiator support (near where my regulator was) and has the power wire for my electric fan, headlight relays and the power feed from the stud on the firewall. As noted above each power wire has its own fusible link.
