BIG 3 Wiring Upgrade Kit - 1/0 Gauge Cable - 1994-2004
These kits fit 94-04 Mustangs.  
 
Big 3 kits are necessary with more amperage draw ie: upgraded fuel systems, audio systems, and/or upgraded intercooler pumps/fans. The kit includes 1/0 (zero gauge) cables that upgrade your power and grounds, they also introduce a fuse holder to the system.  Big 3 kits are always recommended when stepping up to a higher amperage alternator. 
 
This cable is high quality ALL COPPER made in the USA welding cable for maximum conductibility.  Beware of cheaper kits you see elsewhere on the web, they almost always use CCA wire (copper clad aluminum) which has half the amperage rating as this cable!!
