I have a AEM 1052U ECU, came with UEGO 02 sensor and cables with in line controller resistor.
The plug that should be connected to the front of the AEM ECU has:
orange - white - blue - green - brown - red - black wires.

I'm trying to find which among the wires that has a 5V reference so I can use
to my Race Technology digital dash analog to monitor my AFM.

I spoke to AEM tech, he told me "none" of these wires has 5V reference, it all happens inside
the AEM ECU. Is this true?

 

Any help?

 

Use this PDF for the +5V reference. It's to install a speedo calibrator. See Page 4 - Connector C101 Yellow/Blue wire is +5V power
