    Hello all, I have a 2008 5.7 Double Cab. The other night a "fluffy" (squirrel) got in the engine compartment of my truck at ate off my MAF Sensor connector.

    I noticed when I got in and started the truck, it turned over then wouldn't idle. I always have a ODB reader connected and the codes clearly pointed to the MAF sensor, so wasn't hard to find and the nest he was trying to make.

    Needless to say with the connector gone I had no idea what wires went to what pin on the MAF connector that I bought to replace it. I found some wiring diagrams but was hoping someone could confirm for me.

    I hooked it up like this and it starts right up and most of the codes have cleared except for a P0113. It had 3 others before and the truck idles now.

    Here is the connections I made with the aftermarket connector (bought on Amazon):

    Pin 1 (Red wire) -> Blue/White
    Pin 2 (Blue wire) -> Green/White
    Pin 3 (Green wire) -> Blue/Yellow
    Pin 4 (Black wire) -> Yellow/Black
    Pin 5 (Yellow wire) -> Brown

    Thanks

    Can anyone take a photo of their MAF connector/cables and PM to me?

    I know you said you already saw diagrams but I'll post this anyway.
    According to this, you have it correct.

    I'd take a pic of mine but it seems different on my 2014.

    For future reference, you can find wiring diagrams here..

    You could try cleaning the MAF and disconnect battery for a bit. Some obd readers don't clear codes as well as others.
