Not to step on any toes here, but a starter will never pull 300 amps! (unless it is bursting into flames and killing everyone within a 200 foot radius)!!!
Typical toyota starters, under full draw, will pull between 7-11 amps.
Mine pulls 7 amps.
4 ga wire is fine, although, when it comes to wiring, "the bigger the better" DOES apply, think of electricity as water in a pipe....the bigger the pipe, the easier the water flows.
