Default Where do the plugs go?? (Driver firewall)

Im just finishing up reinstalling the intake manifold and i can't remember where these two plugs that are circled in red go and what they are for.

The round one (black) is for my oil sensor relocation kit..

See what sensors aren’t connected !!!!...one is probably the TAC motor and the other is probably the purge solenoid. See what the wire colors are !!

Both look like they go together and should be for the knock sensors. The clip on the larger connector should clip onto a bracket on the intake. I personally eliminated the bracket and just tucked the wires behind the manifold.

I found this picture from a search for you rather then telling you to search yourself. Figure I need at least one person on here who likes me. Anyway, in the picture if you look at the drivers side rear of the intake you will see a bracket attached by the 2 rear most bolts. It does a 90 degree turn up behind the fuel rail. The clip attaches to that with the connector facing rearward

. Sorry I couldn't find a picture showing it actually attached.
