LM-1Wideband Install?

[eclipsed123]

I just bought an Innovate LM-1 wideband and have a few questions about the install. I already have it installed in place of the factory 2nd rear o2 sensor. What I did was just cut the factory sensor off and left the harness. My plan is to wire the analog output of the wideband into the factory o2 sensor harness so I can log it through dsmlink. For those who are not familiar with the LM-1 there are 3 wires on the analog output of the wideband controller (White, Red, and a Bare wire). The white wire is for the actual wideband output, the red wire is for the narrow band output, and the bare wire is a ground. The factory o2 sensor harness has 4 wires blue, white, black, and another black wire. I already wired the white wire from the analog output of the wideband to the white wire from the factory o2 sensor harness and I ran the bare wire to a ground. The only thing I need help with is the red wire (narrow band output) on the wideband analog output. I don't know where I need to wire it into or if it even has to be hooked up. Sorry for the read but I wanted to be as descriptive as possible and maybe someone who has already hooked an LM-1 up like this before can offer some input.

If you are using the stock front 02, there is no need to use the one on the lm.

Did you fit the wideband sensor about 5" before your cat ?
Run the wideband wiring up the firewall & then in the car.
The gauge has a female slot on the back to plug a cable in
that you will have to make up if you wanna (plug to usb)
Of those std 4 wires, the 2 blacks are needed & the other 2
are pre heating ones from memory.
Cheers !

please update your profile
i would guess you have no cat
so there would be no problem using the rear O2 spot
and for your set up there is no need to use the narrow band simulator
unless you want to remove the O2 in the O2 housing

Okay I took the time to update my profile sorry about that. No I don't have a cat. So your saying that I don't have to use the narrow band simulator unless I removed to front o2 sensor. If someone will verify that then I guess my question is answered.

Yes, thats correct
I have an LC-1 connected this way, it works perfectly

Not to thread jack, but are there any dis-advantages to losing the rear o2?
