PLX M300 Wide Band and AEM EMS

I tapped the 0-5V to the AEM p&P harness, but when I installed the wideband I tapped the 0-1V cable from the wideband onto the ECU cable. I prefer to cut the Harnesscable than the Ecu cable, they are not in good shape after I installed the greddy emange last year.

When you first put an AEM EMS in place of the stock ECU the wire from the primary 02 sensor (in header) goes to pin 16 on the AEM EMS and the EMS can see the narrowband signal.
When you install a wideband you remove the primary 02 sensor and unplug it where it goes over the transmission. I left the connector there but bound it in a plastic bag with electrical tape.
The wire from the wideband sensor follows the same path as the original cable. I mounted the controller over on the side wall of the engine bay. The wires from the controller then come through the grommet on the firewall and you connect the power up as indicated in the instructions. The 0-5V signal taps into line 16 (in the extension harness in my case. This is the line that has the covered connector under the car.
You then calibrate the AEM EMS so that it knows that it has a wideband signal coming to it.
Unless you are using a stock ECU or another that can only accept a narrowband signal there is no reason to connect the 0-1V to anything. Mine is connected to a narrowband gauge for the hell of it.

When I installed the wideband I was runing a SC with the stock ECU. I replaced the stock sensor ( Before the cat) with the wideband sensor. Since the stock ECU can

I see. 1V to OEM ECU, 5V to AEM EMS. That sounds right.
Does the AEM have a profile for the PLX?
