I have a autometer O2 sensor but i dont know where to connect it,, could uy please guide me in how to install it to the O2 sensor......

 

I would like to know about this one too!

 

do you mean you bought a gauge to see if ther car is running rich/lean?



If so you there should be 3 wires, a red to 12v+, a black to ground, and the wire that goes to the o2 sensor. You have 2 choices for that wire, you can run it through the firewall and connect directly to the o2 wire, or if you look at your ECU there is one connector that has 16 wires. There is 1 solid black wire. tap into that wire, that's the one that comes directly from the o2 sensor

 

i have ried connecting it to the solid black wore in the 16 socket connector but my o2 does not show anything

when i switch on the car the o2 goes full and when it is at idle it shows lean......... then when i rev it hi the o2 still remians in the same positin onlty 1 light is present showing the car is lean.....am i doing something wrong is it suppose to be like this.......shoud the lights go up when i rev it .....please advise?

 

It does take a couple minutes for the O2 sensor to warm up. Did it keep doing it after you've driven for 10 minutes?
