2000 Civic: Need help identifying two connectors

[sharktooth]

Hey, folks;

 

I need some help identifying two electrical connectors. The look very similar to each other, one is gray, and one is blue. They sit on the wiring harness just away from the PCV breather box. The connector is round, and fairly large.

 

I have replaced my engine, and I'm not sure where to connect these two things. I haven't been able to locate them in the service manual. It's a 2000 civic DX 1.6l automatic.

 

Thanks,

sharktooth

 

Edit: I believe they are junction connectors. I found C115 and C116 in the service manual, on 23-26, but I still would love to know what they connect to.
