ok first things first. i did not buy this. it was in my car and not hooked up.i no they dont help you much. but id still like it to be hooked up.ok well i need to hook up the wire into the sensor wire.but where do i do that at?idk how i would do it at the ecu in this mess.

and in the engine bay the o2 sensor wire has 2 black wires and one blueya everywhere ive read say theere supposed to be red black and white.so im confused.where does it go?

Get you a multimeter and find out. Should be a power, ground, and a 0-1v signal wire. Unplug the connector and ch-ch-ch-check it. It should take you less than 5 minutes, and then you don't have to take someone's word on the color wire to use.

Wire color, though useful, is rarely accurate enough to use as your only guide for hooking ish up.

@ ECU - White wire, pin 29

I pulled my harness through. for some reason mine is really long lol. but it will only really read at WOT. the rest of the time its just being retarded (autometer is steady though..)
