Any one have a Wiring diagram for 2001 F250 (Ground Problem)

I believe I have a ground problem with my truck. If I am correct the short would be related to a harness or group of wires that are causing these codes to be set during a KOER switch test.
The codes are P1670, P0703, P1536, P1780, P0565 through P0569.
The codes are EF signal, Brake switch A&B, Throttle switch B circuit malfunction, Parking brake applied fail Circuit, TCS circuit and a bunch of the Cruise signal malfunction codes.
I have checked the connections at the IDM and the PCM no burned wires or ends. Any one have a CD or DVD that shows if all these codes are related to a group of wires near the IDM or PCM?

Thanks, jim

Are you doing the "Switch" test correctly? If I am not mistaken, (And I have AE also) It seems to me there is a "Procedure" you need to do while doing this test. It will show fails if you dont do the "Hands On" part. (Maybe it is working each switch in a certain order?) Not sure.
One of the best places for information like the wireing diagram though is Our local library subscribes to it for all makes and when you go in to look somthing up it only costs like 10c a copy!
