I have an 04 express 2500 4.8 I have had to do a bit of work to since I bought it used. I have another problem I cannot find a solution to anywhere. When I bought it. It was missing the mass air flow sensor and the plug had been cut back about 6 inches. I replaced both with new but the replacement plug has different color wiring. I have looked everywhere and found multiple color pin layout. None have the colors I have.

I have: 2 tans, 1 pink, 1 yellow, and 1 black w/white stripe.

Thanks for your time.

Perfect. Thank you.

At the risk of sounding ungrateful, how do I determine D from E? If I knew the ECM pin for the IAT I could OHM back between the two tan wires. Unless you know an easier way.

again, I am very grateful for this information. I am light years from where I was.

 

That is odd... Test with volt meter to ground and E should have some voltage while the other shoes 0?
