I had one in my 96 2.3l. It was an aftermarket one from the parts store. Mounted on the steering collum kinda on the top left side. That way I could still read the speedo, fuel, and temp guages clearly. If I remember right, there are 3 wires going into the coil pack. one of them will work, I think it was a green with black stripe, but not really sure anymore. I do know that I just Taped into all of them untill I hit the right one. It's pretty easy. One wire reads correctly, the other two read half of what the actual rpm is.
