I hope you find it helpful.

Way back when I installed mine, it was recommended that you tap the power & ground into wires at the ecu. Going to alternate sources could affect the reliability of your readings. I don't remember specifically which ones I used, but if you find a pinout, you should be able to figure out power & ground.

For the remaining two wires, it's up to you what you want your ECU to see. You essentially cut (not splice) your O2 wire at the ECU and solder in your wire of choice. Make sure the wire you solder to is on the harness side, not the NBO2 side. If you want to use your WBO2 as a narrowband O2, solder in that wire. If you want to datalog and tune, you need to run the other wire and disable open loop in your tuning program. Do not wire both.

I'm going to switch to a less permanent setup soon, I haven't figured out how yet. Good luck with your install. ;D Hey dude all you do is instead of cutting d14 you skin back the insulator and solder a connector to it. do the same with your ground and power. then all you have to do is plug and unplug your wires.
