Help!

Hi guys, I'm a newb here from Red Deer Alberta. I am currently rebuilding a 1997 F-700 4x4 chassis to build my motorhome on. I have replaced the rusty cab with a premium rust free F-350 crew cab cab complete with a minty Lariat interior that doesn't smell like a wet dog and I'd really like to find a pdf'd wiring diagram for the F-350, it had a 7.3 diesel in it. I am making the the dash, instruments, and controls mate with the cummins as well as retaining the power distribution center with the trailer wiring relays etc. any help would be greatly appreciated. Sorry about the Jeep handle, it's my fun ride and will be dragged behind the 700 for some life adventures. I was sent over here by the guys on expeditionportal.com. If anybody has any questions about swapping a light duty cab onto a medium duty truck fire away, there are some BIG differences that I've overcome.

Does the F-700 also have the 7.3 in it?
What year cab is the F350?
What wiring diagram do you want (cluster, power distribution, ignition, ....)?

The cab is from a 1996 F-350 with the 7.3, the F-700 has a mechanical 5.9 Cummins. I want to use most of the desireable features of the F-350 wiring like the trailer charge and back up relays, I would like to use the IDM module relay for the hold in circuit of the Cummins fuel shut off solenoid, I want to put a pulse adapter on the transfer case and keep the speedo working so I'll have to use part of the PCM functions. The alternator is already upgraded to a single wire Leece Neville 200 amp unit, so as you can see I'd really like as much info as I can get. I have the Alldata subscription but it is component by component and I'd like to find a complete schematic, I work better with the big picture if you know what I mean. There is a pile of wiring that I will also be eliminating due to the Cummins being mechanical and I'd like to remove it completely, I'm not the "wrap it in tape and hide it" kind of guy. I'd rather remove it if it is non functional. I don't really need the in cab portion as it will remain pretty much as is.
Thanks for the reply,
Mark.

The PCM has nothing to do with the speedometer.
Sorry I can not help you with the whole wiring diagram and I just have the system by system diagrams also.

You need a set of diagrams like this one on ebay:
