Hey guys, little new here. Long story short, my engine caught fire and now I'm almost done repairing everything. I recently got a japanese engine wire harness since I was having a hard time finding a good usdm one. The shop I got it from modded the harness for me also so it'll be plug and play with my ECU. I got the harness in. If anything its longer and needs to be shorten, or tucked since it reaches over to the driver side of the engine block rather then over the passenger side.

I used a few wire harness diagrams and starting labeling each plug like so.



Now theres one plug that I'm not sure about. Which is:


^ In this photo, that plug is tapped along with the Fuel Temp plug and one of the Secondary Injector. The three plugs that I've yet to come across and eliminate based off the diagrams I've used is the AWS, AVC, and EGR, yet it's the last and only plug left.
Plugs I've got labled are:
-IAT
-o2
-IAC
-TPS
-Water Temp
-Knock Sens.
-Purge control
-Crank angle's
-OMP
-Coolant lvl
-Wastegate/Turbo control
-the 2 T-Stat plugs
-Fuel Temp
-Injectors
-trans plugs


Also while I'm at this, haha, I forget what this port is for:


AND I'm temporarily gonna use a MBC, and is this the correct way to hook it up?



Any help with ID'ing this would greatly be appreciated. The only thing holding me back from completing this would be those things above, and waiting for the local MAZDA dealer deliver me the orings/rubber grumets that sit in between the secondary fuel rail and LIM. Also I'm doing the full non-sequential setup and eliminating the air pump if that info is needed. Thanks in advance

 

What color are the wires going into the plug that is in question?

 

Turbo control solenoid (the one that is attached to the AVC).

The Japanese harness only has one connector for the AVC.
No AWS, EGR (blue), or EGR (Yellow for solenoid), the only cable needed to be extended is the water temp sender connector which is used for the dash gauge and the blue connector for the ECU needs to be swapped.

The port labeled red is for the coolant line running to the throttle body.

Not sure about the last question.

 

Yellow with blue stripe
and
Dark grey with white stripe

 

Nice! Yea I double checked on the AVC. On the new one I got it didn't have the solenoid, so I was stumped there. Then I looked at my old charcoal'd one, and I seen it on that. But seems like I won't need it anyways . Thanks for the help!
