RE:  Wire size/source

Summit racing also offer complete kit with wire/box in variations from OK 
to show look.  

Ron (aka cheap a ron) had inquired about wire size in replacing batty 
leads/gorunds and was gonna go gonzo cause he had some free wire.  Well, 
IMO, once you go past certain level, you are kinda fooling yourself.  
Attention to terminating the ends (crimping, soldering, anit-corrosive 
treatment) may be more important in the real world.  Here is Kelvin's law 
from old Audel's:

The mnost economical cross-section of a conductor is that for which the 
annual cost of energy wasted is equal to the interest on that portion of 
the capital outlay, which can be considered proportional to the weight 
of hte copper used.

Area of copper conductor (circ. mils)= 593*I[(cost of elect*hours)/wire 
cost*interest]**1/2

Where I=amp for h hours/year
wire cost = dollars/lb
interest = annual percent interest, including depreciation and taxes
2g=257.6 cir mils;0.1591 ohms/1000 ft
6g=162.0 circ mils; 0.403 Ohms/100 ft

Do the math.
