The horn relay ground wire goes to the steering column per black wire into the column and grounds when you touch the horn button. That black wire is grounding out inside the column somewhere.
Try taking the black wire out of the plastic horse shoe connector and see if it will blow with everything else hooked up. That will tell you it;s in the column.Here is the color wiring harness in the electrical section it's a life saver if you have electrical problems.
