Update. That is the wrong triangle o2 diagram . The one I actually have has the pink ignition wires as the square o2 do
I am doing a green /blue dbw to dbc on a red/blue ecm harness conversion. Does anyone know if I can swap the front o2 connectors on this 01 6.0 harness. The triangle style connectors are on here and I want to switch to the square white ones because one of the triangle o2 connectors is missing off the harness .
If I keep the triangle o2 configuration, after I do the conversion for the red/blue pcm, will these work with the red/blue pcm??

If you are using a red/blue pcm with a green/blue wiring harness you can use any connector you like. If indeed you have a pink wire at each of the front o2 sensors, the power for the heater circuit is sourced from the fuse block,and not the pcm.

Reason: added info
I know you answered a similar post yesterday, but this is a different harness. The one yesterday had the front triangle o2 connectors but no pink ignition wires. This was a factory red/blue dbc harness.
The one I'm posting about today is a green/blue dbw 6.0 harness that is being converted to red/blue dbc using a red/blue pcm.This also have front triangle o2 connectors but these have the pink ignition wires for the o2's.
I didn't realize it until I actually looked at it...

I went to the junkyard and the only triangle connector I found was from a 06 Envoy but it was the connector tied to the actual o2 sensor. The conductors are aluminum, tin copper, or copper clad... do you think I could wire this in to the harness where the other one is missing?
The one on the harness is black, this one is gray.. it's the same setup... would it make a difference??
