No 4wd Shift interlock fuse blows 02 f250

No cruise, Removed shift interlock soloniod, 4wd does not work, replaced shift motor, and there are no lights on. Removed relays from 4wd circuit and unpluged brake light switch and then replaced blown fuse #34 with a 20 amp fuse and the wireing started smoking. Shut off and quit smoking and fuse blew but I can not find where it came from. Any one have wireing diagram for this

I don't have a diagram but I experienced a similar issue. I found the shift interlock was controlled by a fuse that kept blowing. After lots of searching I found, on this forum, the master cylinder was leaking BF all down the wiring harness where they plug into the cylinder and caused a short. I disconnected the plugs and replaced fuses and was able to get the shift interlock to open. What I found was the cruise suddenly doesn't engage but I assume its from the shorted unplugged wire. I have not replaced the connections and my cylinder is still leaking but at least I can get it into gear.

I've been chasing other issues with the suspension so this took a back seat. It's on the to do list but just haven't spent time tracking down parts. This might not fix your issue but it is something to look at. I drive an 02 F250.

If you look at wireing diagram power goes from fuse to brake position switch. I have the bps unplugged and it still is shorting out.

On another note I had to replace the fuse block about a year ago as it had all kinds of problems and blew the fuese about 3 months later. The truck does have 285K miles and has been beet on, No snow plow though
