Replacing & wiring AEM wideband

I have a AEM LSU 4.9 wideband with gauge, that I want to replace my secondary sensor with, so that EcuTek can use it, and have it output AFR/signal to the gauge as well.

Does anyone know what wires do what on the stock O2?

Thanks!

I might be wrong, but I'm pretty sure the wideband sensor has more wires than the stock narrow band secondary sensor so you can't just hijack the wiring.
