Hey guys, i apologize if this have been posted here before but it seems like i can't find the last piece of my puzzle on doing my single turbo harness. I've research and research but couldn't find what I'm looking for, so I'll turn to the experts.

Where does this go? Its a 2 pin and color codes are BG(black and green), BL ( black and blue) wires, and it goes on the blue 10 pin connector. Posted the actual connector and harness for my reference. Thanks in advance

Potentially the EGR plug per this post:

Darn thanks bro, I saw that on my research before but got confused on the WL which is cooling fan relays in the beginning of my blue plug:

WL BG XX XX Y BrB BL
X BrW BY BrY BW R Br

WL - Cooling fan relays
BG - EGR
Y - 1st Gear
BrB - TPS ground
BL - EGR
BrW - Pressure sensor
BY - +12 Injectors
BrY - Fuel temperature sensor
BW - +12 to solenoids
R - 2nd gear switch
Br - Neutral switch

Looks like the WL white blue wire is by the middle of the plug. I guess this is the USDm version.
Good to know the difference between the two. Again much appreciated for the input

 

The grey connector is the smog/air pump connector. FSM Z-28

 

Hi, jbust I gave you my PDF file I did for my single convertion with everything you need, like connectors number, quantity and the place to buy!!!

Sorry for my english, I'm from QC.

 

Wow! Thanks a lot this will make my life easier repairing the connectors.

 

I'm pretty sure its for the EGR due to the color code on the wires, but I will double check it.

 

If that is what you want to believe, however the EGR solenoid is L/Y & B/W and the EGR function sensor is L/G and Br/B and is a blue connector. The air pump is the only thing the engine bay that uses that connector and has that wiring.

You can proceed however you like but the FSM is the document you should be referencing.

 

My apologies, you are right about the connector on the air pump. The FSM is really confusing lol. Since i deleted my air pump long ago, I will be removing all of these clutter on my engine bay. I'm using a PFC and i wanted to simplify and delete all that are not being used. Any more suggestions which i should be deleting from this harness? I am also looking at the white plug with 14 pin and researching which i dont need from here:

O YR Lg X X YW X Br
B G GY L W BR LG Y

O - Speedo input
YR - Reverse lights (power to lights)
Lg - Neutral (ground)
YW - Temp gauge
Br - Fuel temperature sensor
B - Dash cluster ground
G - Speedo input
GY - Reverse lights (power to switch)
L - 2nd gear switch
W - 1st gear switch
BR - Thermo fan switch
LG - Neutral switch
y - Electrical load input

When i removed the harness from the car the LG - neutral switch wasnt connected to anything,
Any thoughts? Thanks in advance
