I have a ‘91 DLX Pickup, 22RE, 4x4

I opened the hood today and found a dangling wire broken off. I traced it back to O2 sensor..
I have no idea where this wire terminates or how I would splice it back into the system.
Anyone else been down this road?

 

On my 1986 22RE the O2 sensor wire feed into the pigtail near the Brake distribution fitting.
Not sure where yours is cut but look at those wires to see any cut.
There was a similar post as your where they peeled back the wire wrapping and saw the cut wire.
Follow the O2 wire in this pic to see where mine connects

 

Joe,

Your picture is very helpful.

The O2 sensor wire on my '91 is on the passenger side. At least I know where it terminates.

Thanks so much!

 

Passenger side? Might be different end location but this is a start to look.
I sent him this pic as well as I forgot I loop the pigtail and this shows better where it attached on my truck.
It attaches to the female plug that has the gray shielded wire in the harness.
All that black tape is factory applied
