hey man, is this just like a silver edition autometer tach? If so I just put one in my friends civic and how you set up the shift light is to run the white wire to the instrument light fuse, you take the fuse out and push the wire up into the spot, then put the fuse back in over it. The clip on the end of the shift light wire should plug into the one coming off the tach. I hope that I could help you out!
