Easy to hookup, mind you it says it takes "most v belts" not all so if you are like me and your project car uses 5/8 belts you'll need to swap it out not hard but would be good to have in the description for those like myself that are first timers when it comes to building a hot rod and going through the fun of converting from 6v to 12v
