I went to change my O2 sensor on my 2000 Chevy Blazer and noticed that the male connector on the driver side coming from the computer was missing. Don't even see the wiring at all.Any ideas on what to do?

 

Helped a buddy with a similar issue with his starter.

We went to the salvage yard and looked for the appropriate wire. Found it, followed it to the loom, and clipped it with plenty of length.
Found the same loom on his s10 pickup, and we found the broken wire. Fixed with some heat shrink, electrical tape and a new loom.

I would advise something like this procedure, but someone will probably post the wire schematics soon enough.

 

Thanks that's what I came up with going to the salvage yard and look at one off theirs
