ECMlink AEM X series wideband wiring?

[Malrun]

90 Talon TSI with ECMLink.

I'm using a stock O2 (front) and a AEM 30-0300 X series kit (rear). Wideband
I'm not getting the proper reading on ECMlink, It's only showing Linear. My tuner said we can't go farther because of this issue.

Now I'm new to wideband terminology. I've read 3 different ways to fix this issue. Off the wideband gauge pigtail, I have 3 wires the rest are cut.

Black- body ground
Brown to Pin #24 (Sensors Ground)
White to Pin #15 (EGR Temp sensor)

I swapped the input in ECMLink (to EGR) just to check if it works and it doesn't. I was told to connect the white wire to Pin #4 (Currently on Pin #15). Is this correct? Do I snip or splice into this pin#4?

Here's how I wired mine, but I kept the OEM NB and added the WB downstream. You will need to use the NB simulation but I can't really speak to that.
AEM Red/12v to pin #107, black/ground to #106, white/analog 0.5v to #15 (EGR Temp), and brown/analog sensor ground to #24 (ECU sensor ground). Followed the guide from ECMLink: https://www.ecmtuning.com/wiki/lc1install

It's nice to have the factory o2 just in case.

That would be wired correctly. You say in link even with it set for linear its not reading at all? When you log/display raw voltage for that input it just sits at zero?. That would be either gauge issue or wiring connection issue. The x line when wired this way and set to linear, then manually enter the voltage and lambda off the chart will log dead on, if it is logging but just off vs gauge face. Then you need to set the values. .5V min .58 lambda, 4.5v 1.23 lambda.
