okay as the title says I am having problems with my 02 sensor... its actually not the sensor but the wire that connects to the 02 sensor... the o2 sensor is bolted to the header and the wire that comes off the 02 sensor to the connector is there but the wire that connects to it is not there... would anybody be able to tell me where the wire comes from so i can trace it and extend it... 91 nissan 240sx se

There should be part of your harness that runs right between the top of your head and the firewall. Your wire for your o2 sensor should be somewhere in that loom. That same part of the harness has a ground that bolts to the back corner of your head.
