Ok so my o2 sensor wires got burned and such so a guy tried to rewire them and it worked for a little bit but now it's throwing a code again. So I bought a new o2 sensor and a new connector with about a foot of wires behind it that go back towards the ecu. The only problem is the wires that come from the ecu are colored and the wires on my new connector are all white. So my question is how am i supposed to wire this up correctly?

Thanks

If I read that correctly, you bought an O2 sensor specifically for an LT1, and a harness "pigtail" for the LT1. Are you saying all the wires on the sensor are white, AND all the wires on the harness pigtail are white?

 

Like this.

 

Alot of the delco pigtails come that way in all white wire with no instructions at all....

 

The o2 sensor wires were colored but not the one's for the new pigtail going back to the ecu so I wasent sure but I found shbox's refrence earlier and i've already got it rewired and it hasent thrown a SES light yet and hopefully won't.

Now all i've got to do is figure out why my fans don't come on and find two bolts for my catalytic converter .
