My daily driver 72 GT6 had everything working on it and then one day the OEM horn button just popped out into my lap. I have put it back together and installed it but it wont work now. I am sure all the parts are back in and it seems to only go together one way. Is there a secret trick to this? It seemed fairly simple and strait forward. I can manually short to the column and the horn works. I am stumped.
