AEM wideband wiring help.

[thang nguyen]

I jsut bought an AEM wideband gauge type A/F controller and confused on how to specifically wire it up. If anyone has done this before please give me your wiring instructions. Thanks. Oh and do I replace the old O2 or run it at a separate bung?

its very simple. one power, one ground, and i think 2 wires are serial wires to interface wiht a engine management sys.

ground to a ground, run power to a constant power supply when the ignition is on. and your done

as for the o2 bung, yes you should run a new one around 6" from your turbo..

If you are using the same AEM Gauge type UEGO controller I am, you can put it in place of your factory o2 sensor, the controller has a configurable output, you can set it up to replace the factory o2 signal to the computer. It is a little more in depth, if you need to ask how to wire it up, you should probably just have a new bung welded up. Did it not come with wiring instructions?

I bought it used with the Aem ems but lost the instructions. I have the redtop's ecu pinout diagram but confused of the two wires that does into it and where abouts.
