I have a Fummins project. 04 2wd drive CC SWB lariat swapped to 05 FX4 with dash and Harness swap. 6.0 powerstroke truck. I have everything swapped over. The Tach, Fuel Gauge, and Oil Temp gauge all work. I have no Odometer or speedometer reading. The interior lights do not come on and I do not have power to anything when the key is in ACC position. AC/Heat climate control reads wrong outside temp, but will not send 12V to the blower motor in the Heat or Cool positions. i've checked fuses and relays. Any suggestions on what might be the issue.

The pics are of a pig tail under the dash behind the fuse panel that is NOT plugged in and it does not fit the fuse box anywhere. Not sure if its my issue or not?

 

ANY HELP???

The Plug in post one is for the adjustable pedals. I am continuing to look and search. TO RECAP:
I have power to windows when key is in RUN
The drivers side window will actuate in RUN- No other windows will operate at all
I have Tail and park lights but no head lights- will not get 12 volts
No flashes or signals
AC/Heat blower shows it to be on, but no voltage to the blower motor.
No interior lights
WHEN THE KEY IS IN ACC
No power to any electrical components.

THOUGHTS- i've got a main source of ACC power somewhere that is not properly connected. ANY IDEAS? 05 F250 FX4 6.0

 

A bump hoping someone will chime in

 

How much of the Harness did you swap? Did you change any Modules?
Was any of the 05 wiring harness's used other than under the dash?
Just trying to get as much info so I can check the diagrams.
