How to install air/fuel gauge
its the wire harness on the first o2 sensor on your header and youre going to want to do it before the grey harness,,,,, not right next to the sensor but on the other side of the connection harness. theres going to be a white wire with a black stripe and just tap into that

Between the sensor and the plug, tap the black wire. The green/yellow stripe wire from the cig lighter will give you 12V and you can ground it to any known ground. Mine is grounded to the engine block (front right corner, you'll see the strap running to the frame), put a ring terminal on the wire, undo the ground bolt, add your wire and bolt it back down. Make sure you have both wires in there.... your engine must remain grounded.
[IMG]i/expressions/face-icon-small-smile.gif[/IMG] i ran a wire from the o2 sensor on the hedders to the hole in the firewall under the glovebox, then up under the dash, all the way to the drivers airvent, where i mounted the gauge in to.i took a probeing light pointy thinggy, and found the ground and the 12v ignishon wire from wires that are pluged into the gauge cluster. tapped in and it was the black wire, of the four, from the o2 sensor.
