my car came with a dual gauge pod on the a pillar, but they weren't hooked up. one is a boost gauge and one if air/fuel gauge. how do i go about hooking these up?

 

The A/F guage taps into the 02 sensor purple wire on pass purple/white on driver side. On the back it should say which wire is which(power/ground/sendor.

Does your car have a turbo or s/c? for the boost gauge cant help ya.

 

on the back it has a red, black, and purple wire. where is good place to tap in for the power? and where exctaly do i hook the purple wire?

 

For power you can tap into the power accessory fuse in the panel on the side of the dash. For the boost gauge, you can hook the vacuum line up to one of the manifold ports on the driver side of the intake. If it's just a boost gauge and not a vac/boost gauge, you won't move it unless you're actually making boost.

Ps. The purple wire needs to be spliced into the purple wire on the O2 sensor.

 

thanks for the help. yeah its a vac/boost gauge. where is the o2 sensor wire located?

 

Driver side of the car on the exhaust manifold.

 

You can hook to the O2 sensor harness wire anywhere between the sensor connector and the PCM plug (pin C8 or C20).

Just to make sure you understand what you are getting into, the A/F ratio gauge is going to do little more that swing wildly back and forth from lean to rich in "closed loop", providing little more than a psychedelic light show. At WOT, it will move to "rich"... and the stock, narrow-band O2 sensors aren't able to tell you any more than that.

 

figured it wouldn't do much but its there might as well ahve it function and light up.

 

I would ditch that gauge and get an electric FP gauge. Ditch the boost gauge (or in your case...vacuum gauge ) and install a nitrous pressure gauge with accompanying hardware (ie...solenoids, lines, bottle, etc ).
