Default EJ20H wiring diagrams. please help

So im in a bind at this point.
Im about to do an EJ20G swap into my GF8. when i bought the engine the harness was so torn up that i had to get a new one. After 2 months of searching for an EJ20G harness with no sucess i ended up buying a EJ20H harness, sense the engines are extreamly similar i figgured i could use the H harness to run the G engine.
Looking closer at the harness i noticed some major diff. between the G and the H harness. So what im going to have to do is take out the old EJ20G engine harness and replace it with the EJ20H. also the wiring harness is a bit diff. also. the colores are diff. and the guages of wires are diff as well.
so this is what im looking for...

EJ20H wiring diagrams from a subaru manual

i know i have posted this up before, but now im just stuck between a rock and a hard place, i found some EJ20H diagrams, but they where hand written/typed and i dont trust the accuracy of them. my engine is ready to go in, and i got everything i need to do the swap. so now im just trying to get the wiring done and ill be boosting.
if someone has these i would greatly apretiate it.

thanks
kirill

i got some EJ20G 4 plug ECU diagrams and they are a bit diff then the H harness.
I am a little familiar(sp?) with the G harness, and the H is a bit diff. instead of having all of the engine controls go in one part of the harness like the G, the H splits of and 1/2 the harness goes from ECU to engine and the other 1/2 of the engine plugs run thrue the interior harness before it goes to the engine . i can make it work, i just need to know what wires im plicing and what not. its not hard to figure it out, its just hard to figure it out if you dont know what wires your looking at.
