I was wondering what you guys are running

 

Part number for the sensor.

95' Buick Park Avenue 4 wire heated.

 

what year make and model o2 sensor works with that harness

 

I don't know. It's the sensor that tpi parts recommends to use with their harness.

This is from Rock Auto's catalog shows for the NTK part number. It may not be complete nor correct. YMMV

I bought the ntk o2 sensor so as not to buy the wrong sensor. it was way expensive though

 

How much you pay?

 

73 shipped but I should get some kind of discount for multiple purchase on shipping

 

Who did you buy the sensor from?

Rock Auto has them on closeout for $21.79. Even their regular inventory is priced at $36.79.

 

guess I got ripped off then. I will try to cancel the order

 

You can build the conversion harness for real cheap with packard weather proof connectors from mouser.com

 

yeah I am trying to cancel the order

 

Just a heads up for anyone interested: Rockauto has the NTK O2 Sensor (Part # 21002) for $13.57 (not including shipping). Pretty much cannot beat that price!

Good luck all!
