i need the end of the harness that the 02 sensor plugs in to on the passenger side my headers burnt mine and my car is running like crap

 

To my knowledge you can't get just that. You would have to buy the complete wire harness. Alternatively you could try splicing hte wires and using a wire connector if you have enough slack. Or steal part of the wire witht he connector off a junkyard car and connect that to your existing wiring harness.

 

Harness pigtail (from the pigtail list on my Tech Page)
1994-1997 front O2 sensor
GM p/n 12102741
AC-Delco #PT368

 

I stand corrected!

 

that part number from gm parts direct is bringing up the connector for the master cylinder?
