I got a AEM Failsafe Wideband and have everything wired up except the output to the ECU. I am running a 97 integra GSR with a OBD1 to OBD2a Conversion harness to a P28 chipped with chrome, my question is this, which wire to I run to the ECU for it to read the signal to adjust to? There are a couple that it could be for datalogging and such however I think I just need one for the signal to the ecu to read. I have read many things and some say one thing others say another but most people are using a s300 or the aem ems.

 

I assume it's the white wire I connect to the ecu in the pin where the narrowband would be.

 

Usually you can select what pin the wideband input is on. But most use D14.

 

That's the only way it'll work in Crome. But unless you're using the Gold rom or upgrade to Neptune, you can't run it in closed loop with the failsafe because it doesn't have a simulated narrowband output.

 

I'm not using the failsafe part of it for this set up. I just didn't like the way the standard uego looks so I got the failsafe one for an extra $40

 

You would wire it up the same way for every chrome.
White - 0-5V signal output.
Brown - You want to connect to a signal ground so the EMS and Failsafe are on the same ground plane.
