how to hook up an air?fule gauge?

[Let Me Drive]

hay guys just want to know if anyone has any photos on where the O2 senser is and how to hook up the air?fule gauge i have bougt.

also where is the best place to hook the boost gauge to and also where to hook the voltage gauge..

they are all the the center concole so any info of where to run the wires would be great!

hey scott,

the 02 sensor is the front pipe in the engine bay. if you are on the right side of your engine bay (on the side directly in front of indicator) look into the engine bay youll see the turbo heat shield and a large exchaust pipe going on a 45deg angle downwards under the car. on this pipe is a cigar/injector looking thing with 3 wires, thats the 02 sensor. the wires are heater / heater and ecu signal. the two common colours are heater and the other unique colour is ecu signal

nice so that mean i splice the wire of the gauge to the ecu wire? and should i do this at the senser or at the ecu?

it would be a bit easier at the ecu cos then the wire is inside the car and on the right side of the firewall otherwise youd have to feed the signal wire through unless its an external mount guage

You are looking at the ECU from the side, the top of the ecu is on the left.

Just remove some plastic shielding from the wire 29 and tap your guage wire into it.

If you disconnect the wire from the ECU youll just overfuel and run rich, the car will still work but best not to cut/remove it.
