1996 840ci LKM issue

I have a problem with my fog lights staying on all the time. One day I left home and when I got to my destination turned everything off but noticed that my fog lights were still ON. Checked the fog lights switch, unplugged the wires from the switch but lights still stayed ON even with the wires unplugged from the switch. When I unplugged the wires from the lights they went off, but soon as I plugged the wires back on the lights came right back ON and stay ON. I went to my local dealer and was told that something must've shorted in my LKM and that I need to replace the LKM. They quoted me $800+ for the LKM and supposedly another $400 to "program/marry" the LKM to the car. This sounds outrageous to me just to have my fog lights working correctly. For now I just went ahead and pulled the fuse that controls the fog lights/horn off, and have no fog lights or horn. Any ideas how I can go about fixing this that won't cost that kind of money ?
Thank you very much for your assistance and help !
