I recently discovered that my oxygen sensor connector on the engine harness is missing. Any ideas where I can find a replacement? I contacted a few sellers on the board but they will only sell the entire harness. My last alternative is to splice mating aftermarket connectors on to the O2 and engine harness. BTW, I have a '90 GXL.

 

just solder on new connectors...

 

That wire is shielded so if a problem in the harness and want a quick fix, just run it directly from the O2 sensor through the firewall and splice into the harness at the ecu.
