Can someone verify this?? for an 95Impala i dont think 3 feet "total" will be enough? anyone that has done this please pipe up!

Dude get like 8 to 10 feet. Better to have more then too little. Plus it's not to expensive and you can use extra as a common ground or single for large amps

still not clear on- do all the cables have to be the same gauge? i just wanted to order garys h/o battery cables for h/o alternators would those gauges NOT be ok for the big 3? and would those hurt my 140 amp alt if i install them before i get my h/o alt?

I'm not sure I understand your question(s) in your post, but will take a stab at it.

The Big 3 cables don't ~have~ to be the same gauge, but why not. You'll be getting one length for the ground (-) approx 5' MAX (Cutting a 3' piece for the GND from the engine block to radiator support, and using the rest to go from the battery to radiator support which you'll prob have to cut down in length from the remaining 2' to have a nice fit), and then one for the 12VDC from the alternator to battery (+) 3' MAX.

Gary's cable's are a good upgrade, they'll go great with the Big-3.

There's no possible way upgrading to a heavier gauge would hurt the 140 Amp alternator.

Hope this helps.

this is where I buy all my wire from. He has good prices and yes it maybe for marine but it should last forever in our cars.

Always handy to have a supplier like this on hand, but I went with a local welding supply outfit, and even had them swage the connectors on (One for the Alternator, one for each end of the GND cable from engine block to radiator support, and the other shorter GND cable where it also goes to the raditor support).

This website seems to not be working anymore. Is there another place with similar prices besides the $4+ ebay one?
I still recommend a local welding supply house. Get it right away, and you get to look at some cool toys while you're there!!

Is it still necessary to get the big 3 even when you have a optima yellow top with POWERMASTER CS144 STYLE ALTERNATOR?

Its very benifical regardless of what you have, no it is not nesessary but it will help keep voltage constant

Did this along time ago. I will say that you might as well take out the OEM wiring as it will just be useless. As said earlier in this thread, electricity will take the path of least resistance which will be the bigger cable so your OEM cables will become useless.

i did the innovative wiring upgrade. didnt realize how hard it was to flex and manipulate the thick cable. actually used pliers to contort the cable ends since it was too hard by hand. eventually it worked out. hardest part was getting the old wiring out. i have on here a comparison of wire thickness. it did help my voltage drop when at the light. but i eventually got a 300amp alternator.
