I recently puchased an Z and had it on the lift for the first time yesterday and seen that the square wiring harness connectors are hitting my headers. One side of each connector is already melted. What all do I need to replace and where could I purchase them? From what I understand those connectors come with most header kits and you use the rear o2 sensors up front when you do a header install, is this correct?

Thanks for all your help guys.

Don't think you can get just the connector, but you could get one of the extensions and take it apart.

You need the extensions and probably new 02 sensors since that first connection is from the sensor wiring to the extension and the connector end of the sensor is probably compromised. As you're installing the new sensors and extensions slide some 1 1/2" thermal sleeve tubes over the system and use metal tie wraps to hold the now sleaved connectors and wiring up out of the way. You can drill some small holes in the front of the tunnel plate to run the tie wraps through. (These tips brought to you from the school of hard knocks and melted connectors :o)

Thanks for the help guys. When I order the extensions do I just need to push the pins out of the connector and only replace my melted connector or what? Is those thermal sleeves and metal ties available from jegs too>?

You should be able to either use the connector body by removing the pins (push the locking detent on the pin with a flat blade screwdriver), or the whole connector by splicing the wires.

Either way, cheaper then buying an O2 sensor.

The sleaves are available through Jegs and you might find the metal ties in the exhaust section. I didn't try just replacing the plug because I didn't know where to get one at the time.
