if it is a true high output alternator and you purchase it through me then all of them will come with copper 1/0 gauge ring terminal on the B+ terminal and the casing for ground. I always do the big three upgrade on any system along with additional battery before I decide to go the Alternator route. Where ever you get your alt from make sure it comes with a dyno sheet to many people lie and tell you yeah this thing will do like 300 amp and when you get it and use a clamp amp meter it will do like 150-180 at full load and 50 amps at IDLE lol. you might as well stick with stock alternator in my opinion. GO BIG OR GO HOME!!!!
