Best source for automotive wire

Some tips having wired a number of cars completely;

• Get good crimpers, I use several different ones depending on the application. For Packard connectors, I use 2 different ones to get a good crimp
• Not all Packard 56 connectors are the same. GM used them as well (probably Ford as well) but the GM ones specifically are different. They can work many times but something you really need the Mopar version
• The spade terminals for the headlights are bigger (wider) than what you usually see, you need to get ones specific to headlight (I think they are .312" verses the normal .250")
• I order rolls of wire, but its handy to order purple, yellow and orange. The other colors you can usually find locally
