I plan on doing a Big 3 upgrade on my car this weekend. Has anyone done the Big 3 upgrade on an HR?....is it different from a DE?, or can I use a DIY from a DE?, and what would anyone suggest for the wire gauge I should use?. Thanks

 

hey dude are you talking about the grounding kit? I did mine last night and made a real diff in my opinion.......Cheap too

 

well kinda....the big three is upgrading the ground and power wires in your charging system

Definition: the "Big Three" upgrade means improving the current capacity of three cables: 1) alternator positive to battery positive, 2) battery negative to chassis, and 3) engine ground to chassis. Some people replace the factory wiring; others add additional cables to the factory wiring. This instruction is to add cables to existing OEM wiring.

however if you don't mind pm or email me anything you got in the grounding system I plan on making my own (ordered the filters btw)

 

Cool, did you order from national speed? Here is the link http://www.courtesyparts.com/Merchan..._Code=GRND-Z33

I got the 7 wire for the auto in black........great kit

 

And that fit the HR?

 

yeah email this guy.....you need the 6 wire kit......makes a big diff........my auto shifts faster now

z327@maxground.com the only other kit for the HR i believe

 

A grounding kit is only two parts to the "Big 3", there is no wire going from the alternator + to battery +. Also, all grounding kits are 4 gauge or smaller. Ideally what you want is 1/0 gauge for your big 3.

 

Thanks B5....that actually helps me out allot in making my own.... Jason can you take pictures of your cables, or if you can shoot me the lengths of the cables...I'll post a DIY for the HR guys as soon as this project is done

 

You really cant see the cables after the install.......I was in a rush to put them on and didnt measure any thing.....

 

Take a look at this website and see if your layout is any different. It also tells you the lengths of each wire. This is also where I got my grounding kit from.

 

Yes the lengths are alot diff.....but then again we have the hr

 

It still gives me an idea for the HR...thanks.....Jason did you buy the stillen grounding kit

 

would 10 feet of 0/1 be enough or should I get more?, and Jason can you please take a picture of the installed wires if you don't mind?.

 

sure I will take a picture. tomorrow.....I didnt buy the stillen i bought the maxground kit I posted the link earlier......To be honest with you Drew I would buy a prefabbed kit, I was going to make one my self as well but I was just to much trouble

 

Duh......I even read that you bought that kit. I thought about it, but I love working on my car. I have been thinking about buying one, but then getting bigger wires, but that would just bump up the cost so I'd rather see one built then make my own and post it.

 

i understand.....i wouldnt replace any thing i would just add to what is already there

 

please take pictures if you end up doing a DIY

im in the process of doing my stereo and would like to also know this and where to put the wires

 

Ok so I am confused. It is called the Big3 because you are replacing only 3 wires with bigger ones/adding to the existing ones and it does the job its suppose to with no problems. Why do these kits you guys keep pulling up show 5-6 diff cables that are connecting to places not used in the stock setup? Why would you do 6 cables when 3 can do the job and look less tacky? IMO ground wires in colorful variations running all over the place isn't much of a visual mod. So why?

I could be completely off so correct me if Im wrong...

 

A grounding kit is a grounding kit, the big 3 is the big 3, they are different things which serve different purposes. The big 3 is more for the guy who installed an aftermarket stereo with lots of power that's having dimming issues. The grounding kit is so that your car overall has a much better ground connection.

 

So how do you know if you need the 5 wire or the 6 wire kit for the MT?
