If you want to run one, just for the "added safetynet" of knowing what your afr is like, its simple. For a gauge, you will just need the sensor in the downpipe, and then the power, ground, and signal wires hooked up. You will then need a gauge that also has signal and power hookup, as well as the signal wire from the sensor.

The sensor needs power/ground because it is heated.

i really like zeitronix because it is extremely accurate, and because u can expand it.
for now u can just get a wideband. then later u can add boost and EGT.
u dont need to wire anything after u wire the brain in for the first time, everything is plug and play after that.
u can even have audio and visual alerts and u can set the values on your laptop.

to log AFR or any other value (given u have the sensors) u dont need a gauge or display of any kind. u just plug the brain to your laptop and u're set. logs up to 16 hours of continuous data.

zeitronix is always coming out with new gauges and updates, when u are tired of your old gauge u can simply buy a new one, it's plug and play.

ZT offers these gauges for now, more to come:

paid 30 bucks for a bung. ran the sensor wire through an existing hole in where the transmission tunnel would be in a RWD car. perfect. wiring is very simple, just need a pack of 3 dollar tap in connectors from radio shack and tap into 5 points at the ECU, power, ground, tps, rpm, sensor ground. no need for pricey boomslangs.

i got it with the LCD mount which i mounted onto my dash. i will upgrade to the map sensor, and EGT probe in the near future. for those two there is no additional taps at ecu. . u get accurate boost, and egt temps along with afr in one nice lcd display. i hate a pillar gauges. this does it all.

furthermore, u can log it with evoscan or mitsulogger, and it has its own logging software which is nice. no free air calibration needed, it self calibrates. no sensitive grounds like the lc-1, can handle lots of dirty power.

after extensive research, i liked it best and im happy with it.

Other than that, you just need to have good power and ground. You do not need to splice into the ECU harness unless you are looking for additional features besides monitoring your AFR - i.e., only if you want to also log RPM, boost, and other parameters.

For ease of installation, the LM-1 is the easiest, since it is a self-contained box, so you just install the O2 sensor, connect it to the LM-1 and plug the LM-1 into the cigarette lighter. Anything that feeds into a separate gauge will require a little bit more time to install, but either way, it's a really easy procedure. IMO, if you're comfortable with installing something like a radio/head unit/cd player in your car, you should have no problems with a wideband.
