What's the cleanest way to wire a cut off switch

mine is so clean that i had to put scrubs on when i installed it. lol.








I just finished a complete re-wire with a painless kit. i have a 4 post switch. the big wire is from battery to starter only. then i have a 4 ga. wire that feeds my fuse box. my alternator is wired to the voltage reg. then i have the charge wire going to the starter post. my alt is completely isolated. when i kill the switch it cuts all power to the car from the switch forward. everything is killed.
