LITEON 0225 gonna attempt mt1339e, what else is needed??

hi im gonna fit an mt1339e and spi from a benq to my liteon 0225 as im annoyed with the kamikaze hack. i have the mt1339e on the way and i have the spi already. is there anything else i need for this as ive seen differnt versions of it in images. i read somewhere i need a switch for the wp? is that necessary or just convenient. any advice with this would be great.
