Default O2 sensor connector missing?

Hi.
Sergio here
Cherokee xj pioneer 87
As you can see i found the female connector there.laying down.
But where is the male connector?trust me. I look everywhere and nothing. Seems last owner cut it off.
question is . Where the male connector must be located or where should be locate and bolted. Maybe im missiing something.
Worst case scenenario somebody can take a picture of the male connector cables from the O2 to the cable bundle . I think i can find the cables inside the bundle and confirm the cable colors then solder a New cable/male connector.
Thx guys

The male connector on an '87 is usually a separate pigtail. It doesn't plug directly into the main harness. Follow the main engine harness back from the firewall. You're looking for a single, separate wire with a two-prong male plug on the end. It's often taped up or tied back to the main loom. If it's missing, you'll need to find those two wires (usually tan and orange) in the harness and splice a new pigtail in.

Is a 3 Wire connector and i know i will have to find the wire in the harness..

I ve checked the fsm and seems is in the same harness of the temp sensor and knock.
and also seems the male connector snaps on chasis but its gone
seems i will have to buy the knock and o2 male connectors.
