I have a ProEFI installed on my 350z, along with MAP sensor and fuel pressure sensor. Now I also want to connect a signal wire from my existing AEM Wideband Air Fuel Gauge to provide an A/F signal to the ProEFI. Can anyone tell me which wire to tap into to provide this A/F signal and to which lead to connect it to on the ProEFI?
Thank you.

P.S. I know its the 0-5V wire, but if you know the specific wire color that might help even more. AEM gauges are very popular, I'm sure someone knows.
