I did some testing. I ran power to #3 on the picture and the relay clicks when I press the horn button. It also causes lights to dim. I am thinking ground ?
I ran ground to # 1 and # 4, both times the relay would buzz. When I run ground to # 2 it sparks, but strange I do not get power when testing this point.

I tested the horns again and they both work. I could not find a ground wire on the column. I also have a 71 Challenger, I looked for a ground wire on the column but could not find one there. Those horns work perfectly. I also attach a couple pics to show you what you are helping me with. Its so close to being done.

I appreciate any suggestions or thoughts.
