Piggybacking Wideband output from Dyno

Hey, My dyno dynamics Dyno does not have any anologue outputs to connect to your ecu (ie wideband output for in software logging)

It does have its own wideband sensor which goes to a box first which I assume is where it does all the converting and then outputs to the Dyno... So Id imagine there would be a 0-5v and a earth output in those wires... Would I be able to piggyback off those signals and feed them into a ecu? or would this cause ground offsets or anything else undesirable
