i will be keeling the factory harness and fuse panel just would like to know if anywhere anyones done such a swap
i am pulling the body this week and starting a cab swap to a 46 mercury
but i would love if someone has done something similar and has any idea

The job you are proposing is harder with the 7.3 than a cummins because fewer guys swap a 7.3. But that said, Alldata is one source for wire diagrams. They are at alldatadiy.com
I am sure others can chime in with more expensive sources of wiring layouts.
I encourage you to replace any wiring/connectors that seem questionable. Use good quality, finely stranded wiring to dupicate the quality of the o.e.m. wiring. Look for critter chewing on the insulation or vibration caused wear spots. Definitely replace the under valve cover harnesses-the newer connectors are going to be more reliable. Look for corrosion in the connectors.

cool thanks a lot man i know what i have on my plate and i am ok with that... i beat to my own drum and this is something i have wanted to do for a long time...
i plan to try and simplify the harness for the PCM as i will not have airbags i will not have seatbelt sensors and so forth
the truck i have was running i drove in to where it sits and started to strip the interior and prepare for lifting the cab of the frame and remove the harness from the cab and re and re in to the 46 mercury cab
the dash will be stripped to metal and i will be using the mounting locations for the column and will attach that to the cab of the 46 well
i notice your also from BC retiredsparky i am in the interior and hoping theres no critter eating my wires

See my posts in this thread. This is the harness for my 1973 7.3 conversion. I kept cruise control and the electronic shift on the fly intact.

The PCM was located in the cab by the parking brake pedal. The IDM for the injectors was hidden behind the drivers side plastic inner fender (but outside the engine compartment).
You can eliminate air bags, window control wiring, door locks, etc without a problem.
One important connector you should retain is located above your knees under the dash. This connector faces down for connection to a scanner or computer for reading codes, resetting codes, reading engine operating data, troubleshooting. Do not discard this wiring.

What can I tell you realistically?
Figure out what systems you need /want to retain and then look at a wiring diagram. Pull the desired wires out of the existing harness looms and then throw the rest in a pile. You're going to have a heck of a time with this project if paring down the harness is your hang-up.

thanks i have actually almost got everything together in the other truck..
the body's mounted to the frame now and the front core support is mounted with the rad and intercooler the floor was sectioned out as well as some of the firewall...
some small things like the clutch and brake petals i have in but will have to modify the hoses / some sensor wires ..
as for the column i gunna try and get mounted this weekend i got it rigged up in the truck in aprox place of where i will now want it
my realistical question will be do i need the cluster ?
what year was the truck u took the wires and motor from ?
is the box u have beside the idm and pcm the GEM that has the in cab fuse box with it?
as u kept the cruise control ... did u kept the wheel and column or just the switches
out of the 42 pin wire off the motor i got 19 wires(+1 key power and 1 POWER ground ) ( =21wires ) that go to the pcm and 11 wires that go from the 42 pin wire off the engine to the IDM.... thats 32 of the 42 wire connector off the motor
now...
from there i have 5 wires + a ground from the IDM to the PCM
i dont wanna fry my PCM thats just why i am asking about it

No.
2002
No, 2002 had a stand-alone transfer case control module for the 4x4 function. I retained the shift-on-the-fly so I needed that. I didn't use the 2002 fuse box.
Used a 1982 E150 van steering wheel because I didn't want the new look. All of the switch resistances are the same as the newer pickup.
You are going to end up cutting A LOT of wires out of your harness and shortening/lengthening a lot of wires in the process.

made some progress today got a shortened version of the harness back in the truck and with everything layed out and hanging in there including the column the PCM the IDM both fuse boxes and all the aux relay boxes in
i get a few lights on the cluster but no gauges move ....
when i go to start the truck for the momentary trial i did the truck sounded like it could start as it did crank
as of now i am gunna do a few things and see what happened
i think i will now just wire in a WTS light from the wire that feeds it threw the cluster
also will wire a CEL from the same bundle
and a WIF light
all the head lights and brake lights and 4 way flashers worked with there respectable switches
the horn relay clicked over
so i think i an getting closer and closer by the day
