First of all - hi to everyone

Im not a new guy in the car scene, but barely new guy in Porsche world. My first 'meeting' with Porsche been quite dramatic, and im still having this drama for over 5 years now...
Long story short - heres a 'rebuild' if i could say that - album:

If you browse all the photos - you will understand whole story... But just to make it more clear again. Im a Jap cars guy - been so all my life, been building racing cars, drifting cars, and later of got my self in restoration business, thats how i spent last of my 10 years - restoring cars. And as always - theres has to be least 1 Porsche in your life (air cooled i mean). As i had 996 GT3 before, i was kind of itchy to get my hands on 930 Turbo... So - i got it, and thats how it all evolved. Car was pretty badly rebuild before (if i could say that? lol) So i tried my best to get it back on the road. But - the guys who disassembled it prior to metal work - is already a past, and he neither left me pictures neither made a list of parts needed. So i got all the body work complete and now started back with assembly, and heres the trick - when you try to assemble some thing that you never disassembled - and neither you have a big clue about - its like banging into the wall with your head.
I had a nightmare with wiring - as even the Kroon wiring harness said NO to repair it. Thats for beginning. Managed to fix it, changed like dozen of burn wires, short circus and non original plugs. Updated relays, connections and etc - but still have few wires in questions and few plugs that i dont even know where are they going...
Trying to restore all the parts that i put back into the body now, and trying to figure out where all the fuel lines, brake lines and AC lines go... This have been my latest night mare - as body has been welded - so means no oem holes for brackets. Was browsing hundreds of pics online trying to understand where what goes - but my head is still dizzy from all the different years and models and lack of pics... So i would really appreciate if some one could point me in the right direction on the:
AC lines routing
Brake lines routing
All the cables routing over the center tunnel
Fuel lines routing
These are the 'first' questions / advice needed.
Oh and yes - i have owners manual - it helps but not that much some times...
Thanks for the help in advance, and hope i will get my head filled with more info about Porks soon
Oh so i will leave these 2 pics here - the day i bought it:
And at i think a middle point of metal work...:
