1994 Ford Bronco Blows Fuse #18 with ignition turned

I own a 1994 Ford Bronco EB, that one day while driving home from hunting, I noticed the speedometer was not working, nor the digital odometer... Upon further investigating I found fuse #18 was blown, tried replacing and everytime I turn the key it blows.... This fuse controls: Speedometer, Overhead Temp/Compass, Airbag, 4WD Electric Shift, and Overdrive from what I have gathered... As I can drive, but no speedometer/odometer, no compass/temp, no 4x4 at all, and the tranny shifts hard with no overdrive... Not sure if it is a coincidence, but I have never used the 4x4 on the fly before that day, and used it 2x that afternoon, driving no more than 15MPH at the time. Any help would be appreciated. I have already done a thorough wire inspection on the entire undercarriage of the vehicle, transfer case included. Specs... 1994 Ford Bronco EB, 5.8L, AT, I have replaced the automatic hubs with manual WARN hubs, still have the push button 4x4 and 4x4 lo on the dash that was functional up until that day.

I would start by disconnecting components that are on fuse 18. Easier said than done, but here are some diagrams from the EVTM. I would advise you get one, it is the single most useful service manual you can get for your truck. You can find them on eBay. Just did a search and here you are http://cgi.ebay.com/ebaymotors/1994-FORD-F...sspagenameZWDVW

Hope this helps.

Good luck,
