We use American Autowire for our builds.The ez-wire and painless use a bulk head connector.AAW and Ron francis use a modular design.They are much easier to work with.The AAW kits come with headlight switch,dimmer,and ignition switch in there kits.The best thing about them is they are upgradable.
For instance say your build and budget you would like to have A/C and power windows but you just can't swing them right now.With the AAW kits you will get all the wiring you need to do this but it wont have to be installed until your ready.With the other bulk head kits you have to do something with all those lose wires hanging around.The AAW kits are plug and play.So to speak.
Depending on your needs we sell both kits
AAW15 259.95
AAW22 359.95
