O2 sensors
In the midst of butchering my '99-03 wiring harness and am trying to figure out what type of sensors they take and why the wire on the right has 3 wires where as the one on the left has 4; with the beige wire splitting in 2 and going to God knows where.

...I believe it is out of a 99-03 truck...not sure buddy gave it to me. After looking it over the connector on the right has a purple\white wire cut from it. Anyone know what pin on the ecm it goes to?

I still have the rear O2 connectors I took off of my 99 Camaro harness let me know if you want them the colors wont match exactly but they will work.. I'm not sure if the PCM you are using is the same if they are they wire like this.
Bank 1 Sensor 1 is drivers side 02 Bank 2 Sensor 1 is pass.
The black wires are ground and the pink 12V switched.
These go to Blue connector.
26 TAN HO2S Low Signal [Bank 2 Sensor 1]
29 TAN/WHT HO2S Low Signal [Bank 1 Sensor 1]
66 PPL HO2S High Signal [Bank 2 Sensor 1]
69 PPL/WHT HO2S High Signal [Bank 1 Sensor 1]
Bank 1 Sensor 2 and Bank 2 Sensor 2 are not needed and can be tuned out.
