Big 3 in an Impala

[k3n12ock]

Anyone ever do he big 3 in an 00 -up impala? If so, any tips on doing it? I see that there's like 3 wires from both the ground and positive. I've no idea what they are for. Anyway, advice please?

Our cars are almost identical, I have an 04 Monte Carlo. I did the Big 3 in mine recently:

Okay so there's the ground from both the chassis and the engine block right? How did you do the wire from the alternator to the battery since I didn't see any pics. Was it a bitch to get the bolt out? For me it looks like it because the AC is right in front blocking it.

I haven't done the alt wire yet because I didn't have any 2ga red wire for it, i'm going to be finishing up running my main power lead tonight, which is red 2ga, and I expect to have some leftover so that's what i'm gonna use to do the alt wire. I just went outside and looked at the location of my alt wire and luckily for me it's right on top of the alt with nothing blocking it so I don't expect any issues getting it off. I have a 3.4L BTW, what size is your motor?

Same, 3.4L. Dude, I did the big 3 but I just realized no change because my wire to the alternator is actually going to my stupid starter. I'm a fucking idiot. Once my engine cools down I'm going to switch it up to the alternator. I'm suchs a fool.

Okay. So I upgrades these wires:

-Positive wire from alt to battery

-Negative wire to chassis ground

-Negative wire to engine block ground

-Starter wire to positive on battery

Oh yeah, so I removed the stock positive from the alt. and was driving around and then all of a sudden I noticed my abs fails, battery light turning back on and shit starting to die. I got back home and hooked it back up and everything is okay now. Would I need to replace that wire too because I have no idea where the heck it leads to.

Leave your stock wires alone and just 'add on' basically for the big 3. I have it done in my car, but can't find any of my engine wiring pics.

LOL. Shit happens

That's exactly why I left the stock wiring in place. On mine I just added a pos lead from the alt to the battery, left the oem wire alone. IIRC, the oem alt wire runs to the main harness, it would be a PITA trying to replace that wire. Edited August 2, 2009 by SQMonte

Well, I stuck the old wire back on the alt. Went and bumped around for about 20 minutes and no cutting out on the amp. Looks like the big 3 was a good idea.

Good shit.

I just finished running my power and signal cables and it looks like i'm barely gonna have enough power wire to get the power alt wire done, i'm cutting it close for sure.
