Should be the white wire.

All my other AEM's were the white wire.

10-4. I found a wiring diagram and it shows pin 55 being not used. Does something need to be activated in the ecm for hptuners to see this input?

Wouldn’t be easier just to get a wideband with a serial out to plug it into your USB port on your laptop. If your using standard HP tuner

Or the OB2 wideband that AEM sells.

Haven't tried the EGR trick on the E38's, only the P01/P59 have I done it before.

The OBD2 wideband only works on newer Can based ecms. Like 07-08 up
