big 3 wire upgrade

**cockergod** · 08-03-2006, 02:11 PM

Has anyone done the big 3 wire upgrade, if so did it help with the electrical system and how long did it approximately take to do? thanks. I want to see if it is even worth while to spend the money on to do.

what kind of audio equipment do you have. That will help us decide if you need it. Even if you don't have big stuff it's not a bad upgrade to do if you have lights or anything that draws alot of power from the battery

Yeah i really dont have any aftermarket audio but i have the 05 e fans that draw a grip of power. so i was trying to see if this would help me at idle with the power draw.

It will help. I did it to mine. Just take some wire no thinner than 4 awg and run it over your factory wires. Dont pull off your factory wires!

Go from:
Alternator to Batt +
Batt - to frame
frame to engine block

edit: some people like to fuse the wire going from batt + to alt. but I'm not fused. It took me about 15-20 mins to do

are you just using 0/1 stereo cable? i have about 4 feet of the stuff is that enough?

**twankydeuce** · 08-04-2006, 08:57 AM

4 feet might be enough. Just cut one for the alt to the batt and see how mush you have left. It depends on where you mount it to the frame and engine block.

Here is an idea of where you can mount the wire to the frame and engine block...

i'm new to this... what's the purpose.

better gas mileage?!?!? yea ok

**twankydeuce** · 08-04-2006, 09:21 AM

better current flow. If you have alot of electronics, you wont have as much current draw if you upgrade the wires.

**Luc1f3r** · 08-04-2006, 10:32 AM

twanky, what size wier did you use? 4awg, that shiit looks SMALL!!

**twankydeuce** · 08-04-2006, 10:38 AM

yea its 4awg. I didnt think 0/1 was neccessary

**Luc1f3r** · 08-04-2006, 10:40 AM

gotcha, i got it for my stereo, because it is such a long run i figured it would be better than the 4awg needed.. so since i got a good price i ordered enough for the big 3 also, i think i got it for like $2shipped a foot.... also, it does make a difference, on only 300 watts i would dimm pre big 3, post big 3 i dont dimm on 800 watts.

**twankydeuce** · 08-04-2006, 10:50 AM

word, I would dim alittle and now I dont dime at all with 1200 watts plus some. but I also added bamf'n alternator lol
