Hello all, first of all i know there are probably hundreds of threads on this but my search thing isn't working and hadn't been for some time now.



I plan on doin the big 3 upgrade this weekend and was wondering if anyone had any pics of where exactly everything is located! Also if you have any experiences, advice, specs on anything you would like to give that would be appreciated as well. Well I plan on using 4gauge wire for everything, because that is the size power wire I have running for to my amp. I have about 5 feet of positive an ground 4gauge wire im going to use, plus my ring terminal connectors and some solder to solder the connectors on. again thanks for any input

Sorry man first time I heard of it I haven't done it my self, is your truck 4x2 like mine? Please report how Good is after you do your upgrade

 

yeah I can find it on 04 an up but not our 1997-2003 body styles.


the big 3 is upgrading your alternator to positive on the battery, battery ground to chassis and engine to chassis. it allows more current to flow and doesn't put as much strain on your alternator Because it has bigger gauge wire to help
