[1:14,5] Caterpillar D6T (Help)

cat966g
Hello
I have a project to build a CATERPILLAR D6T!
I need help because I have no idea WHAT to do and have to buy to mount the electronics and hydraulics.
Can anyone help me by sending me a drawing with the parts and how to link to work perfect!
Is there any site that shows step by step how can I mount the hydraulics and electronics?
I'm from Brazil and my English is not very good.

I await an answer.

thank you
