Since I need to purchase a new alternator when I pull the car out, this has been on my research list for the past couple of months.
It seems to me that if you are interested in replacing all of your cables it would be better to buy everything from one place if you can and piece together your own kit.
Personally, I think 2/0 is overkill and 1/0 would work just fine.
There is an eBay user, genuinedealz, that has all the stuff that I'm looking for and I'll probably get my stuff from there. It's tinned marine cable and supposedly very flexible. Here are the prices I've dug up:
(1) 1/0 (25ft) 103.75
(1) 4 AWG (50ft) 84.00
(2) 1/0 Battery Terminal 5.48
(4) 1/0 Cable Crimp 3/8 4.48
(10) 4 AWG Cable Crimp 3/8 9.10
(2) 1/0 Solder Slug Pellets 2.30
(5) 4 AWG Slug Pellets 2.25
(1) 3/4 in. bl shrink tube 2.15
(1) 3/4 in. red shrink tube 2.15
(^^ Prices are total, not per)
Connections:
+ Battery to Toggle Switch (1 Battery Terminal, 1 1/0 Connector)
+ Toggle Switch to Starter (2 1/0 Connectors)
+ Starter to Distribution Box (2 4 AWG Connectors)
+ Alternator to Battery (2 4 AWG Connectors) (unless get battery terminals that accept wire)
+ Alternator In-Line Fuse (2 4 AWG Connectors) (unless get ANL fuse holder that accepts wire)
- Battery to Quad Shock Mount (1 Battery Terminal, 1 1/0 Connector)
- Quad Shock to Engine Ground (2 4 AWG Connectors)
- Engine Ground to Chassis (2 4 AWG Connectors)
If you wanted it legal for the strip just add a cut off, Moroso from Summit is $40, some type of tie down for the battery.
I've done a ton of reading about what's the right way to wire everything up and make sure the PCM runs correctly and blah blah... and the above is what I've come up with. Oh, and you'd want to add battery terminals and an in-line fuse for the alternator to battery connection. I'm opting for better stuff on those items than that user has.
Also, my wire lengths are quite conservative, but I wanted to make sure I had some left over for some re-wiring on my audio in my other car.
