General Wideband Installation

[Mauispyder]

Hi,
I'm finally getting around to installing my Innovate MTX-L
Wideband. I've read much on our forums regarding this. I will be installing in the front O2 sensor location and using the simulate narrowband capability of the device. My question is, is there a good reason I can't use the existing power, ground and sensor leads from the existing O2 sensor?
Seems like it would prevent CELs for heater at least.
Thanks

Trying figure out how to do mine too. Previous owner cut the wires to,front o2 sensor and put the wb sensor there which tripped code p0135 for the heater circuit

Are you referring to just hardwiring the o2 into the harness in the engine bay?

Just hardwire, if your using link. You use existing harness to splice into.

I prefer to leave the OE harness intact should you need to go back to the OEM front o2 sensor later.

Plus the wires you want are inside the car anyways. With the mtxl the wires are at the gauge not the sensor. You don't wire the sensor you wire the gauge and is super simple. Power, ground and brown or yellow wire to ecu.

True, I'm just not sure if I trust myself around all those Ecu wires. My thought was to cut the wires near the original sensor and run/splice them into the gauge in the car. Thus - not cutting ecu wires, using the same ground the ecu sees and not getting a CEL. In addition using the wires from near the sensor enables one to go back to the old system by just buying a new O2 sensor. I am black box /Tactrix btw.
I am open to which method to go with, so I definitely appreciate your input!

Just use pin 76 for the wideband signal. Then you can tap the gauge wire to the cig lighter power and then just ground it by the ecu. It's super easy bro.
