Default 2004 rear 02 sensor to front adapter

Where can I find an adapter to put my rear sensors to my front plugs for my 2004? I searched all day and all I seem to come up with is square to flat. Both my fronts and rears are square. Appreciate the help.

The one on that site is square to flat. Unless I bought plugs off them and spliced it myself, but I would hate to do that. I appreciate it though, maybe I didn't look hard enough, I am using my cell

If both are square will they work without an adapter?

Are you looking for extensions?

Well the fronts are male plugs while the rears are females, or vice versa. They will not match up without an adapter, but now that you mention it I can probably use extensions as an adapter by just flipping it. I thought about that earlier, but for some reason my logic wasnt making sense, I did not realize it would match up.

I know they changed the front o2 sensors in the 2004 to square connections, but any c5 rears should be the same right? I had part numbers for the rears, but one website did not list them as 2004, they had a seperate section.

The more I think about it extensions will not work. I have male rear sensors that need to go into male front plugs. I would need an extension with two female ends. I am not having much luck locating after the cat plugs with female ends. I am just curious what other people who own a 2004 did when they put on long tubes.

Bumping an old thread, I'm having the same issue. LG sent me the wrong adapter twice, I'm out of ideas for 2004 Z06 with LG superpros.
