11 N55 MAF Signal Wire

f87CSdrifterential · 08-20-2019, 08:27 PM

I installed an AEM meth kit on my car. Grabbed what I thought was the correct MAP signal wire after testing all 4 (pre throttle body). Keeps flashing the LED to let me know the expected signal is out of range. Going to move over to trying to grab MAF signal. Anyone have a pinout available? I tried searching, but was unable to find anything. Thank you.

I ran 12v switched from the lighter socket under the armrest. When I first turned on the car to accessory it wouldn't find the MAP signal and flashed the LED for signal out of range. I did have the correct wire.

Then when I went to start the car the kit didn't reset and was still in error mode. I switched to a different 12v switched source and everything works fine now.
