Ek4 Hatch (B16a2) Unplugged Connectors (Need help)

[JdmKids Manny]

Hey guys,

Names Manny, new to the site, I actually just picked up an EK4 and as i'm roaming threw the engine bay, I notice 2 connectors unplugged on the back of the engine block right behind the oil filter.........

The first plug is square, blue in color and has 6 prongs. I found this one Unplugged:

The other connector is 1 prong, black with a red stripe:

Would highly appreciate the help, Thank you guys.

@Vtec6000 will definitely know what connector this is.

Ignore the blue multi pin connector it doesn't plug in anywhere, I believe it's used for diagnostic purposes. As for the single wire connector, that wire looks to me to be blue/red? If so more than likely knock sensor plug.

Yes, thank you so much. I should plug that knock sensor plug/prong back in ? And yes that wire is blue and red, followed it back to the mini fuse box near the air filter.....Another thing..... When I turn the key to the "on" position cel does not come on and turn back off. Trying to pull the cluster to see if bulb is missing or burnt. Once again, thank you all for the help.
