Hello, I own a 2003 ford taurus. I was wanting to replace one of the horns on this car with an older one that I have found. This older horn is most likely 40-60 years old, but still works. The problem is, is that this older horn has 1 wire for + and then it is grounded by a bracket. The factory horn has 4 wires going into it. I'm not exactly an electrical savvy person, so if you could explain this so that it is easily understood, that would be of great help.
By the way, on another subject, this taurus is an SES, this means it has the duratech 30 engine right?
