uhh follow the directions that come with the gauges. For the AF ratio, just find the bungie that comes from the O2 sensor in the header, follow it till it comes together, right off the main wiring harness. There is a purple wire, you want to tap that wire for the AF ratio.

For the rest of the wiring, well if you dont know how to wire a basic light, dont bother attempting this.
