Sorry I can't help more.

I have looked at it but it doesn't tell me which wires goto which ? The stock sensor is black,red and white. What do I do ? ahhh

[sjbsuperman1425]

compare the stock sensors connector to the new sensors connector

i dont have one

[sjbsuperman1425]

i might have my old one still. I'll search and see if i can post a pic tomorrow.

Pretty sure black goes to black (signal wire) and the outer whites are interchangable 12v and ground which turn the sensor on to heat up.

if mbmbmb23 is correct the signal wire on my harness would be the black wire ? since its shielded ?

[float_6969]

Shielded wire on your harness >>> Black wire on new sensor
Brown wire on your harness >>> White wire on new sensor (doesn't matter which)
Blue wire on your harness >>> White wire on new sensor (doesn't matter which)

Oh, and make sure that the brown wire on your harness has 12V+ with the ignition on, and that the blue wire has continuity to pin 115 @ the ECU. If not, the engine may run poorly during cold start and warm-up.
