Link V3, SD and AEM wideband questions

[Goat Blower]

I'm having a hard time deciphering the Link wiki on this particular combination. So I've got V3 running speed density tuned by Shane. I'm switching over to use my UEGO gauge wideband and narrowband simulation for the O2. I've got the Link plug and play harness so I'm using the factory IAT and baro sensor inputs for that. What's the best place to tap my 0-5V AEM output to Link? Front O2? Do I run a separate wire for logging? I think the EGR input doesn't work with the AEM.
