tell me you didnt order that antique Box. The newer white and black ones are significantly narrower than that. That will not use modern cables. Buy the VEVOR knockoff or go on craigslist or marketplace.
Is this the 4 cylinder motor? If it is you have a 16 amp charging system. If it is the 4 cylinder you never spin them past 5250 rpm. If it is the v6 or 3 cylinder opti motor disregard.
