This truck has about 4.7A to almost full 5A draw. Now I can tell you what fuses stop the draw but not sure what to do next.

 

Tag @Auto Computer Specialist hopefully he see this.

 

In the PDC you need to pull the 20A PCM fuse #3. Then the 10A combination flasher fuse B. 

 

Then in the cab the IOD fuse 12, integrated module fuse 13, and cluster fuse 14 in the dash. 

 

This drops the total draw to 0.2 Amps total.

 

I've got a power distribution map but in PDF format.
