Default Need heated O2 Wiring help.

In the process of replacing my engine and transmission I pulled the pins from the connector on the heated O2 sensor harness and do not know where they go back.

Anyone have a detailed pin-out or schematic that shows which wire goes in which slot. I believe it was pink, black, brown, and purple in a 2x2 square plug end.

This is for the chassis end of the harness that goes back to the ECM.

Except for this one little mistake the rest of the swap went perfect.

Thanks!

Take a look at the O2 or car side, whichever the wires are still in the proper places on. Then match the colors.

Perhaps I can look at the pre-heated sensor and compare, but the colors at the connector on teh heated side do not match up. They change schemes after the connector.

I will check the FSM for my 2001 (should be the same???) to see what the connector layout is. I am at work and it is at home, so won't be until tonight.
