Hey everyone so I'm in the process of setting up my ecu and getting it ready to go before I bring it to my tuner but I've ran into an issue. My car is a s14 with a rb25det swap with a wiring specialties pro harness using their IAT sub harness, and I'm using a g4x ngtr plug-in ecu. When I connected my ecu to my computer and get into pclink I put my iat source to an temp 2 and moved the pins 26 to 36 and soon after my noticed my iat melted the brown plastic part. After trouble shooting I realized that my harness previous had the 26 and 30 pins switch, so when I made the initial adjustment to my harness I really move 30 to 36 and 26 to 30. I wanted to see if I could of possibly messed up my ecu by any chance, everything connects fine and I don't think I have any problems, but I'm still seeing the fault code 46 for my An temp 2(iat), even thought I should have the pins in the correct spots.

I cant really make anything out from your photos, but one side of the IAT should connect to pin 36 and the other side to any sensor ground - that could be 26/30/34/50.  If in doubt, unplug the ECU and IAT and use a multimeter to beep out which pins the IAT plug has continuity to.

I was able to get the correct wires where they needed to be and when I tested the connectors where my iat plugs into it gets 5v now, so I’m hoping nothing was damaged.

That is normal. 

With the pull up enabled you get 5V on the ANTemp pin and 0V on sensor ground pin. 

If you deactivate the pull up you should see 0V on that same pin that showed 5 before
