O2 Help

[4wheeldrive]

This is my first post!
I have a 2003 6.0 Chevy gas Engine out of a van (not drive by wire) The forward O2 sensors are $130.00ea. I have 6, O2 that have a square plug but mine uses a kind of a Triangle plug. If I change the plug end, will this O2 work?

Hello 4wheeldrive,

All front O2 sensors on the 1999 - 2003 6.0 L are “Isolate Ground” variants. The rear O2 sensors on the 6.0 L could be either Case Ground or Isolate Ground. As long as the O2 sensors you wish to use as a substitute are Isolate Ground - they should work just fine.

GM used a mix of O2 connectors in those years - flat, square, triangular, and of various colours.
