i have just bought an Air to Fuel ratio gauge, and a boost gauge, and i have the instructions and they aren't very helpful, more confusing. any of yall that have hooked one up can you tell me where and how to hook it up....on the Air to Fuel, which wire do i connect it into on the O2 sensor, and which sensor? thanx in advance

if it is a fox car up to 93 look at the wire on the o2 sensor. 2 will be the same color. use the third wire that is a different color from the rest.

i believe it is white but it may be black. just use the wire that is different from the other two. also hook it up on the harness side not the o2 side. if you ever have to change o2's then you will have to hook it up again if you put it on the o2 side.
