connector question

Hey All

Could someone please explain what the 2 wire plug on the back side of the
mixture control unit is used for. I found it unplugged last night while installing a
Innovate WB O2 controller. Does this affect the fuel mixture by chance. I've been
trying to get this thing to pass emission tests and my CO% is way above spec at 25 mph test. I installed the WB O2 for 2 reasons..to control fuel at idle and mid cruise to pass the emissions test and also to datalog A/F's while spirited driving. Once it passes the emissions test, the O2 signal wire is being disconnected and the CO% is going back to 3.0% but I will still be able to monitor the A/F ratios.

Also is it normal to have a small hole (drilled) in the top of the banjo fitting bolt at the wastegate..or did someone do this to increase boost pressure?
