O2 plug in behind intake manifold

[the sandman]

I have a extra plug in centered behind intake manifold from main wire bundle. I think I have all four sensors hooked up. Not sure what it's for.

Pics??!

Do you still have motion control plates on the manifold?

Post a good clean picture and we can try and help. Also if you can see what color wires are going to it.

If it’s centered on the intake, 99% chance it’s the CMCV connector. If it’s open, congrats you have CMDPs already installed!

Wow. I forgot I took those plates out. Man I guess I need to write this stuff down. Thanks for the help.
