Default Wiring connections for driver side knock sensor

While replacing the starter I managed to yank the wires out of the male connector that goes into the knock sensor on the driver's side. I managed to find a replacement connector including wires that I plan to splice into the existing wires so I have some slack, bit I'm not sure which wires attach attach to which terminal.

The wires coming from the harness are red and green. Not sure if green goes in terminal marked 1 or 2.


Separated wires

Overview of knock sensor position

Anyone know which wire belongs in which terminal?

Break apart the old connector.
There still should be part of the wires attached with the color of each. (Hopefully)

*Update:
I just took a peek at my 05GX.
Green wire goes to the #1 terminal of the connector.

Default Thanks! Also found the wiring diagram.

I also managed to find the schematic. In the course of researching it, it happens relatively frequently during smog pump/ starter repairs as there's not much play in the wiring harness, so I'm posting the diagram
