10 gauge wire from the starter post to the ammeter (this is the only wire on the discharge post)
10 gauge wire from the other post on the ammeter to the alternator post. If the alternator is self energizing, then you only need this wire. If it isn't you will need to run a second wire from the alternator plug to an accessory post on the switch.
14 gauge wire from this same post on the ammeter to the switch (bat post)
14 gauge wire from this same post on the ammeter to the switch for the lights
14 gauge wire from the ign post on the switch to the (+) post on the coil
14 gauge wire from the (-) post on the coil to the points.

If you ever add an electronic ignition like a pertronix, the coil is wired a little different because there are two wires coming from the distributor.
