Im trying to wire my efi but have a few problems. When it say blue/white for example does that mean blue wqith white stripe or can it also mean white with blue strip. Just i have a wire from the afm that is blue with a yellow strip but theres no listing so i dont know where it goes. i thought maybe i had different wiring but the computer and someother thing possibly fuel relay both have 18rg on them. How do i figure out these problems. Anyone in brisbane that can give me a hand would be great. Thanks.

Check everything with a multimeter. Trust nothing. Doing my 1UZ one at the moment and I'm suprised that there are wires the same color coming out of the ECT box that do totally different things just to confuse you!!
The wiring diagrams are generally pretty straight forward. Something like "BY" means blue wire with yellow stripe. I suggest you get someone to give you a hand or just take it very slowly. Last thing you want to do is fry the ECU.

Not every ECU has the wiring diagrams on the cover.
I have a Stock 18RGE ECU and it doesn't have it in it.
the cover was never off until I removed it.
