oxygen sensor
wheres the o2 wire on the TII harness, like where the o2 sensor plugs into. Isn't the knock sensor and o2 sensor plug identical? I can only see one plug on my harness that splits off by the TB sensor, this is for my knock sensor correct? If you can give me some info as to where I'll have to run the new o2 wire to I'd really appreciate it.

It's a shielded cable that comes out of the harness in front of the BAC. Single connection. As the wire is very thin, they do break after a period of time. If you dig into the harness and see the shielded cable, just solder a new wire in place, but make certain you cover the splice, I used heat shrink, and make certain the shield doesn't touch any part of the O2 wire core, or it will take it to ground and you'll have no reading. Some will just run a new wire directly from the O2 sensor through the firewall and splice into the harness just before the ecu.
