Hey everyone

Can anyone help me I've just fitted a AEM air/fuel ratio gauge it has four wires

Red 12v to power
Black ground


White analog output
Blue signal output

First where do the white and blue wires need to be wired to. I have a vipec v44 ecu.

Or will the gauge work with out the blue and white wires being connected

Thanks Shaun

I don't know the specific gauge, but if it is a build in wideband controller with a separate wideband sensor which it must be with the two output wires, then you just need to connect the 12v and ground wire, apart from the sensor itself. The white and blue wire will be used, if the ecu is later mapped with closed loop wideband fuel regulation, or for data logging.
