Circuit Werks is now offering o2 extension harnesses for many General Motors.  Perfect option rather than cutting the harness, having issues with a poor connection and this is also faster and easier.

Designed for the use of custom applications or header/ exhaust modifications.

  • 27" o2 Extension Harness
  • Fits thousands of GM applications Mainly vehicles from 1997 to 2003 GMC, Chevy, Buick, Pontiac, Oldsmobile
  • Loom uses a flexible high temp cover
  • These harnesses vary slightly but will be a minimum 27" long
  • If you have one that looks like this but is gray color it will not work.
Check the pictures to make sure this is right harness for you. I have pictures of both the male and female end of the harness for reference
