O2 Sensor installation question
I'm trying to figure out what sensor assembly to use where. My kit came with 4 O2 Sensors and no way of telling which one goes where. I believe I only need 2, one for each header. Below is a list of the sensors i have. Can anyone tell me which one goes where? Thank you.
All Motorcraft sensors:
DY-1296 FL3Z-9F472-A (Black jacket)
DY-1354 FL3Z-9F472-C (Orange jacket)
DY-1308 FR3Z-9F472-C (Grey jacket)
DY-1346 FR3Z-9F472-E (Grey jacket with black nylon jacket)
Thank you for any assistance,
Tim

Yes you need only two. My Gen 2 Coyote is using DY-1308 FR3Z-9F472-C (Grey jacket) and DY-1346 FR3Z-9F472-E (Grey jacket with black nylon jacket). Only different between those two is the length of the cable. The crate motor only uses upstream sensors. Downstream sensors, e.g. after cats, aren't supported and typically cats aren't on our builds anyway.

Oh awesome. Thank you Paul. Are all 4 of the sensors the same? Just different cable lengths?

I don't know. I don't recognize those other part numbers. I only recognize the two I referenced as exactly the same as what I used in mine.
