Hello and welcome to the board !!! The new horn relay not clicking means it's not energizing...Do you have the schematic for the horn circuit ??? Here's a link to the 70 plymouth factory service manual... link Looking good and testing good are always two different things...You'll have to start checking the circuit beginning with simply grounding the horn wire in the column and go from there...Do you have the column grounding wire in place ???

you can unplug the turning switch harness and ground the black wire on plug. Should get horns. If you do, problem is at horn switch or column inside... if not, problem is somewhere between plug and relay... or relay itsef

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. Dennis
