There are 3 wires to hook up for the (Autometer) air/fuel ratio gauge that I'm trying to install in my car. I've connected 2 of the 3 so far, the live wire and the ground. I'm hoping to get a bit of advice regarding the 3rd wire, the one that gets the signal from the O2 sensor itself.

The instructions say to tap into the wire that goes between the O2 sensor and the brain box, but I'm not exactly sure where that is. I really don't want to splice in to the actual O2 sensor wire, as that runs near the header. Since the wire coming from the gauge isn't heat-shielded (and shorter than what I'd need it to be)...this won't
work. Is there a terminal somewhere where I can connect this wire to? If not, which wire would I splice in to, and where can it be found?

Oh, yes...the car in question is an 84 Rabbit GTI. Any advice would be greatly appreciated. Thanks, folks!
