Im just gonna come right out and say im not the smartest guy in the world. i have a 92 civic SI anyone have any hints or links to diagrams on how to hook up a air/fuel gauge and a oil temp gauge i am totally lost.

 

can't help you on the oil temp, but the air/fuel ratio is pretty simple (assuming you have a narrow-band). There should be a black wire coming off the o2 sensor. At the connector to the left of your header it changes to an orange/black wire. That's the wire you want to splice into for your o2 signal wire. Beyond that, the guage is a red = positive 12v/ black = negative ground ordeal. Really, the hardest part is hiding the rat's nest of wiring you'll have.
