Articles » PLX Devices Wideband O2 Install

Okay so here goes...
They come with a pretty straightforward install procedure. And the device is pretty simple. I mean, you hook up ground, power, install the new O2 sensor, run all your cables and you're done. But I did have to do a little digging to find out how to fool the ECU from thinking there was not an open in the coil wires signal.

Here is what you should have to start, the Autometer converter of course is optional.




1. Figure out where you want to mount everything. If installing with a standalone system, or you plan on getting one, they recommend putting your ground wires as close as possible, which makes perfect sense. So pick a good spot where you can achieve this goal. I plan on using a VAFC in the future, and it will be mounted in my cup holder position, so I mounted the box to the metal frame with 2 tie wraps as you can see in this picture.


2. I also bought the PLX Autometer gauge converter, which turns your A/F gauge into a wideband display. Like this....

So I also had to figure out where to mount this little box. It's not that big, so it's fairly easy to find a place. I used tie wraps once again, to secure it just on the other side of where your gauge bezel mounts in the dash. As seen here in this pic.


This is both devices mounted and ready to go.
