Any ideas what this connector goes?

It is renix wiring.

 

Note from DJ
This information bay or may not be true. I have not verified all of it but it may be what you asking about.
It looks like the C116 connector which is a gray 8 pin connector.
It is used to connect one harness to the main harness.
A, D&H pine are not used
B pin is a black wire connecting the oil dipstick ground to the ground for the 02 sensor
C pin is gray wire which oxygen sensor input to the ECU D9
E pin is violet/white wire for the knock sensor input to the ECU
G pin is yellow/black wire for the knock sensor ground

 

Im talking about the grey connector like the one in this pic.
