AEM UEGO to EFILive v1?

[Tan327]

This should probably be in the v1 forum but it looked pretty dead so hopefully my question is okay here.

I've done quite a bit of searching on this but still haven't found a good answer on how to wire these together. The rest of the install looks fairly easy, just not sure exactly where to connect the white (analog) wire and if the blue wire is needed? Will I need any other wires besides the red, black, and white? Any help is appreciated.

Edit(found this picture later) If I'm looking at this correctly, white goes to C or E and another ground(guessing I add my own ground wire?) goes to D? ..then power to red and that's it? I know absolutely nothing about wiring unless it's Cat5 cable so please dumb it down for me if you don't mind. :grin: Appreciate any help!

Do you have the AEM UEGO 30-4100...?

AEM UEGO blue wire is serial comms, ignore this (tape off).

V1 pin E: connect AEM UEGO analog 0-5V output (white wire) here.
V1 pin D: connect AEM UEGO ground here (black wire; black wire also goes to vehicle/chassis ground).

Yep 30-4100. Thanks, I guess I'm still a bit confused on the ground. If the AEM UEGO black wire runs directly to EFILive, then how does it ground to the chassis as well?

Lol thanks again, so just splice into the AEM's ground. I pictured the wiring being a little differently in my head but it definitely makes sense now.
