Melted IAT

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.
