Need help installing LC-1 wideband kit

[dsmcoder]

I have a 1g gsx with ecmlinkv3 installed. Now I bought the LC-1 wideband kit and I would like to install it in my o2 housing where the stock o2 sensor was and use link to simulate it. Now my question is do I tap the original o2 harness to get this working right? If so what wires go to what?

Help is appreciated

Yes, you want to tap into the wire that goes to the ECU input for the front o2 sensor. You'll find the wire number on this wiki page.

You'll find an ECU pinout on this wiki page.

Okay now I know the white wire goes to the ecm but where do the rest of the wires go, or did I miss it in the guide you gave me?

Which white wire are you referring to? One of the LC-1's wires (either yellow or brown, depending on how your setup is) will go to that front o2 sensor wire. The rest of the o2 wires from the ECU are not used, if that's what you're asking. If you need to know where the other LC-1 wires go to, do a search on here as I've posted it up many times before.

Okay I did a search and this is what I found

Brown - ECU Pin 75 (white)
Red - Accessory power supply
Blue + white - Grounded using same crimp ring
Yellow - not used
Black - not used

Now I have a question, what would I use for the accessory power supply and where would I ground it?

First of all, if you look at that pin number compared to the first link I provided you, you'd see that the pin is on a 2g, not a 1g.

You can use the radio or cigarette lighter for accessory power. You can ground it on a metal bracket somewhere around the center console, if that's convenient. Just make sure to test where you plan on grounding it to double check it's a good ground.

Okay thanks, and yes I did realize that pin was for a 2g, mine is pin 4, I was just posting what you said on the other thread.

Do I need to install the calibration wire or can I calibrate the sensor with link somehow? If I need to install the calibration wire where do each of the four wires go?
