The triangle style front o2 plug is what I'm talking about . This is on a 01-02 6.0 harness. There is no pink wire. I was just trying the verify that this is completely computer controlled because they have no wiring tied to the c2 fuseblock

All the power and grounds are controlled by the ecm if you have the 6.0 computer and harness.The downstream o2 heaters are powered by a fuse in the fuse block. This info can be found at lt1swap.com.

I’m having trouble with my o2 sensors. I have the triangle style shown above, but my tuner says they aren’t getting hot enough to read. There is no power to the heater in the sensor. Can I just run fused 12v power that is only hot when the ignition is on to the sensor? Independent of the ecm? If so which wire is power to heaters and which is the ground for the heaters? I have a tan, a purple, a green and a green w/white stripe ..

I just went through this with my conversion. You need to pull the green and the green white pins from the ecm red connector. I ran a 15 amp fuse in the green wire to a key on source and the grounded the green white wire to the chassis ground location.
