"The big three"

[tmorales509]

Does anyone know where i can get these. I guess the alternator positive to battery positive, batteries neg. to chassis and the engine ground to chassis? I checked on autopartswarehouse but couldnt find em. Is this something i can get at any local auto parts store or is there a website that sells em? Also is this something pretty easy to do or would someone like a mechanic have to do it?
