How much wire do we need for the big 3 in these cars?

 

25 ish ft

 

so that would enough for engine block to battery alternator to battery and chasis ground to battery? what did u use for chasis ground?

 

Damn you need to read up on the big 3 cause if you connected it like that it wouldn't be good...


It's alternator positive to engine fuse block, fuse block to battery positive
battery negative to ground
engine chassis to ground
