it sounds like you might have tapped the sensor into the wrong spot.
the Red/Black wire (singular) is the AIT signal wire on the harness.
the Black/Lt Green is the ground.

Doesn't matter which goes where. But it seems like me like you tapped into the RED and Blk/lt green or blk/blu wires.
if you'd had the laptop connected you'd have probably seen 0° in the intake

i dont remember for sure what the colors were, i went based on that picture that you posted, i cut the third and fourth wire so as long as it doesnt matter which one connects to which other one, i should be ok, no?

on the serious note, the harness turned out to be faulty indeed...
