mine had two black wires and from what i read it was non polar

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?

yeah if tapped into the ones above you'll be fine. Actually I guess if the AIT wasn't seen by MS it wouldn't run at all. So I sill think it's just a matter of tuning your fuel map.

tried to install the pussy magnet this weekend, it fried my coil, lol

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