2nd generation door electrics

[92luxman]

I'm converting my Hilux Pickup to electric windows/Mirrors using Surf parts and have the necessary bits and a chunk of the wiring harness. What I am unsure of is if any relays are required,( I did receive the door control relay with the parts but I am not at the moment intending to utilise central locking) I wondered
if any other relays are used or can I simply wire in with a fuse? Any advice gratefully received.
