I've used most of the Rebel,Ron Frances, EZ Wire but for the past few years I have started using the American Autowire and am sold on them,,everything is included in the box,,you don't have to go and by additional parts. The instructions are easy to follow and broken down in different steps. HRP
Nobody has mentioned "Haywire" I jusy installed one of their E-series harnesses. The quality of the kit is outstanding, very nice. But the manual ****s ***. Very poorly put together. Not for the faint of heart.
American Autowire is the best out there. Full complete kit with easy instructions. Made in USA http://cappshotrods.com/product-category/electrical/customstreet-rod-harnesses/ Real quality, just compare the way the panels mount. Compare what comes with each kit. Because what you don't get with other brands will end up costing you more, a lot more
