So, I picked up my 1987 Jag XJ6 from a previous owner who had installed a "horn button" to bypass the steering column. Essentially connecting the purple/black to one terminal on the button and black ground to the other. I am attempting to take back to the original wiring/system. When I do connect the purple/black to the lower, steering terminal and the black to the upper column terminal, it sounds and won't stop. So, I replaced the relay. Same issue. Then, I moved the steering wheel (turn/telescope) and it goes on, off, on, off etc as if there is something grounding the steering column. I have removed the steering pad and even the brass rod and it still sounds. Interested in any theories to attempt to repair. Thanks so much in advance!
