LS3 MAF Wires
I made a big mistake trying to shorten my MAF wire harness. I have an LS3 Erod and I cut the MAF harness wires before I looked and saw there were two tan wires. Now I'm not sure how to reconnect them. Is there a way of finding out what tan wire goes to the "E" pin "intake air temp sensor signal" or what tan wire goes to the "D" pin "low reference"?
Thanks

I don't know what it is for this car specifically, but it seems like the reference should read around 5v continuous (guessing it's a 5v reference), while the the IAT wire would read something different, but I'm not sure how much different it would be. And the IAT signal should vary while the reference signal shouldn't.
That's just something I would experiment with if it were me.
Pretty stupid to have two of the same color wires!

Tan wire with the 5V is the outside pin (I'm not certain if that's A or E in the post 3 diagram, i think it's E).
