Hello, I am looking into doing the SPI to Zetec engine swap.. I love my fog lights on my sedan, so I was hoping to find another set at a junk yard and install on my wagon when the time is right. I understand I would need to change the switch, but would I need to completely rewire that switch too? I haven't looked under the hood to see if there are wire sockets down there yet, but assuming there aren't. Any ideas please?
