Change order in CHECKOUT PAGE

Hello,

Can someone tell wich file i need to edit so i can change order in CHECKOUT page, so this will be order:
hikashop_checkout_cart - to be before (hikashop_checkout_coupon), and (hikashop_payment_methods) and (hikashop_shipping_methods)?
Basicaly i need to hikashop_checkout_cart be first, not last like is by default.

So i need someone to tell me which is file needed to be edited?
Thanks

Thank you so much!
