Hey Guys

I just need some help here. I'm trying to install a air to fuel ratio gauge in my TII but for the life of me can't find the O2 sensor wire. Does anyone know where it is supposed to be?

Thanks

The o2 sensor is connected to the stock down pipe. There's gonna be a single wire sticking out, simply connect the wire from your gauge to the single wire to the o2 sensor, if everything is connected right, drive around and the gauge should start reading if your running rich or not.

If it isn't there, on the pipe. the wire comes from underneath the manifold near the firewall on the passenger side
