Thanks to the diagram from Mann on the ECM diagram (#2) I found the wire colors. Now my problem is I'm looking for where/what connector those numbers actually correspond to on the plugs going into the ECM. There are multiple of each color in a lot of the connectors.

I'm looking for Rear Sensor 1 and Rear Sensor 2 Signal wires and Reference Wires. Any help is appreciated.

Do you have the ECM removed or you are looking into the ECM connector positions. Each wiring indicates the color. the connecto represent 4 parts to the connection. The connector HT (1) and OX (3) represents the Heated Oxygen Sensors. HT is Right Top Corner and OX is the lower RT Corner. The H5 is the B+ wire which is represented by No2 is top end Left Corner position which is Bank 1 Sensor 1. Adn the Lower Left Corner is the B2 Sensor 1 that is position 4.

Front View of the connector above should look as the position
2 1
4 3
If you need to check the O2 Sensors Always measure the resistance between the terminal of the O2 Sensor
Now coming to the terminal positions on the ECM if that is what you were asking.
Symbol OX1A Wiring Color R-BR (Red Brown) ( Terminal is OX1A (E6 -23 - E1 E7-1) and OX1B is wiring color B-BR ( Black Brown) & terminal is E1 (E6-29 and E1 (E7-1) OX2A G-BR which Green Brown and terminal position is OX2A (E6-22 and E1 (E7-1) and OX2B is Color coded W-BR is White Brown and terminal position is OX2B (E6-25 and E1 (E7-1). Hope this is helps

Yes, the ECM is in the vehicle still. I will study what you just replied with to see if I can track down the connector/wire. I appreciate your time!
