salam to all...
Yesterday got time and did my Big 3 wire upgrade on my cultus , it
was tough as per me as i am not much that of a hardworker ,and not use to
this kind of work:P .The Diy was done by myself(2 hands) and took 1.5 hours to
complete and was a success 
.Things used
8 thimbals big ones
.1 60A fuse to in line with alternator to battery positive wire
.approx 3 meter , 2 gauge wire
.nuts and bolts as required
.thats all :)with other household tools used
Procedure.
this is efficient yet cheap upgrade to improve overall car's electrical performance ..we change three wires accordingly
1st Alternator to battery positive wire
2nd Negative to chassis ground wire
3rd engine block ground to battery negative wire
does Big 3 help in real
yes it did for me there is notice able increase in cabin light, headlights bright,
lights fluctuate less when blower stars ... engine starts early than before...
..
btw was really tired :(but really statisfied after a diy:P:P

60A FUSE


PAINT SCRAPPED OFF FOR GROUND CONNECTION
