Which IAT am I supposed to get? I wish I could just reuse the stock one =/
Which IAT for vortech non intercooled

Thank you very much. I did not know that.
So going with a 05+ slot style BA5000 from SCT like I am, I would need to locate the 2 wires and route them to a stand alone IAT sensor?

The slot style mafs have the iat sensor built in. You do not have to run a separate iat. Unless you are spraying meth after the maf then you need to relocate the iat.

That too is good info. I do plan to introduce meth to my setup at some point.

My slot style MAF required a seperate AIT sensor.

That depends on where you're placing the MAF and whether you plan on spraying meth/water.
That's true as long as the MAF is installed in a blow-through configuration. If it is installed in a draw-through configuration, you would want to run a separate IAT.
Then you will want to run a separate IAT sensor, located between the meth/water nozzle and the cylinders. You do not want to spray meth/water through the MAF.

We need to clear this up this is one area i am also Fuzzy. Which year mustangs did not have the AIT sensor integrated into the harness? my model did not I had to run th esensor seperate while others were using the SLOT maf and harness together.

IIRC, the IAT was integrated into the MAF in '01. It's a moot point if we're talking about aftermarket MAF's and FI applications.

Thanks I thought this was important to understand. So 01+ had the AIT sensor integrated and could use the stand alone Slot style, while the earlier models had to use the Slot style and seperate AIT like i did.

Your car came from the factory with a MAF and a separate IAT sensor. Later models came from the factory with the IAT sensor integrated into the MAF. Either one could use a slot style MAF with or without an integrated IAT sensor. Choosing whether to use an integrated or separate IAT sensor is not dependent on the year of the vehicle, it is dependent on the induction layout (blow-through vs. draw-through) and whether or not you'll be spraying meth/water.

I'll put it this way:
If you wanted to run the slot MAF and make use of the integrated IAT sensor, you would need to connect your current IAT sensor wires to the MAF, the MAF would need to be located after your supercharger and intercooler, and you would not be able to properly tune for meth/water injection (spark vs air charge temp tables wouldn't be able to account for meth/water).
Keep your separate IAT sensor.

My car is done I rerouted my AIT sensor into the side of the TB after my EGR delete. I custome made all my piping as well and welded it.I'll put it this way:

look in this pic you can see it.
I used a slot style MAF as well in a blow thru setup this is how I mounted mine. however after the EGR delete I made my own egr Plate and tapped the AIT into the TB so my temps would be very accurate so my AIT is no longer on this pipe.

Your setup is completely fine. The thing to remember is that the IAT should see the actual temperature of the air entering the cylinders. If the MAF is located where it sees these temps, then the IAT can be integrated into the MAF. FI, charge air cooling (intercoolers), meth injection, and nitrous all have an effect on temp, and the MAF typically won't tolerate meth/water injection passing through it.

Yes, typically the closer you can locate the IAT sensor to the cylinders the better. On my 4V car, I'm running a draw-through MAF with the IAT sensor located in the blower manifold below the twin-screw (IAT circled in red in picture). The methanol nozzles are located in the inlet plenum (pre-blower), so the IAT sees accurate temps here.

What Methanol problems did you have to make you abandon it? Do you know why?
My plan is:
Blower-----> FMIC-------> BOV-----> BA5000 MAF------> Meth------> IAT-------> TB
