I did not, I kept the factory wires in place just removed the factory terminal clamp on the positive side and cut the stud clamp and drilled a hole to bolt on to the sky high terminal on the negative side at the battery, glad my video helped, the only reason I did it.
I upgraded the power wires on the alternator to minimize the risk of a current bottleneck, as I was planning to install a large audio system, which is now installed. The system draws about 600 volts lol 0, primarily supplied by additional batteries. To ensure optimal energy flow, I installed a 280A alternator and used 600A-rated cables. Even the stock alternator, which operates at a little over 100A, would benefit from slightly larger cables, such as 0 gauge. Regarding parasitic draw, I haven't noticed any issues. My truck can sit for over a week and still starts up without hesitation, although I haven't measured the draw specifically. Also might not notice as I'm running 2 deep cycle AGM and 1 lithium 64ah so even if I did it would take over a month to drain and the longest I go is a week at most without driving it.
