Probably a long shot, but...

...I am fitting an LC-1 wideband next week & need to know what the standard connection is for the stock O2 sensor. I have an '04 Monaro. My intention is to re-use the original connection to the original O2 sensor by making up a lead with the correct plug/socket on the end.

I can't get the car on a ramp until I fit the wideband which leaves me no time to source the correct plug/socket. Any help woul be appreciated.

I have a special O2 sensor socket. I think they are 22mm from memory.
I got it off ebay for a few quid. Its a worth while investment.
