For the ignition system, you can't go wrong with 16 AWG automotive grade wire (just because it comes from an auto part store doesn't make it automotive grade). Automotive grade usually costs 2X to 3X more than generic wire. However, I found Waytek Wire sells it at a very reasonable price. Give the connectors and terminals as much care and consideration as you can. Waytek sells very high quality terminals with a heat-shrink jacket that I use often. The cheap crimp connectors with a plastic sheath are just asking for AAA to come by and say "Hi".
