1994 F150 4x4 Anti-Theft Problem
 

This truck was in Alabama for Katrina, so there have been many electrical issues that I have had to work out. I have 1 left that is driving me nuts. The Anti-Theft system randomly goes off when I start the truck. It doesn't matter if I had the doors locked or not when I got in. I can't count the number of times I have driven through a parking lot or out of my driveway with the horn beeping. Thankfully it stops after 5 or 10 minutes, but then the horn will not work until after I shut the truck off and restart it. I tried going to the local dealership, but they said that since the PCM controls the alarm, there is nothing that can be done. I asked if they would at least tell me what connections on the PCM control this so I can deal with it, and they flat refused. And of course, my trusty Haynes manual doesn't show anything on this system. Can anyone tell me what wires I need to cut, short to ground, short to +12v, or short together to shut disable it? I have searched through forums after forums and can find nothing on this. PLEASE HELP ME SAVE WHAT LITTLE SANITY I HAVE LEFT!!!

Seems I forgot to put in a few "minor details". It's a 1994 with the 5.0l, 4x4 standard cab. No key FOB, no chip in the keys, and if I have the key switch in run, I can take it out of the column. I already know that the clock spring is junk, but I wired past that to get the horn to work under normal circumstances. I don't do enough highway driving to justify the $120 for a new clockspring for the cruise control. Any help would be greatly appreciated.

Somebody??? Anybody??? I've seen lots of ideas for 97 and newer MYs having this problem... Anybody know anything about the 94's??? It's driving me nuts.
