No IAT wiring?

I have a 2002 Silverado harness that I am using for my conversion. I had it reworked to remove unnecessary wires by a guy on ebay. I ended up having to unwrap the harness and reroute it to get the fit that I wanted. I just realized after wrapping it all up last night that there is no IAT sensor! I am planning to have a speed density tune done and my understanding is that IAT and MAP is essential. Using the 2002 harness and ECM where and how do I add an IAT sensor? Is it needed if the throttle body has the IAC?

On the truck wiring harness the iat sensor is in with the maf sensor so you might not have seen it in there

Thanks! I removed the MAF since I was going with the SD tune...thankfully the wiring is tucked away in the harness. I will pull the two wires necessary and run them to the F-body IAT sensor I was planning to use in the charge tube.
