To the weekend wrench monkey its a Pain in the ass. I paid 170 I think for the Inovative LC-1 wideband. YOu have to run the led and calibration wires then splice in the 12v and ground, drop the rear shock pull out the fan remove the old 02 (dont waste money on a 02 socket it will not fit, I used a stubby open end wrench), connect the new 02 calibrate it, install it and program the output volts to match the ecm. Took me about 4 hours with a lunch break.
