hi, i need some help with some plugs. on the harness that goes around the engine bay and connects the fusebox, headlight, ecu, ect. on the ecu side of the car there are 3 plugs. i know 2 go to the ecu and there is one left that was cut. does anyone know what it is for. any help would be appreciated.

 

We can't help you without pictures.

 

here is a pic.
i know the 2 yellow go into the ecu. i dont know what the cut one is or the blue plug.

 

Blue goes to the body power harness, so it looks like the wires you have left over belong to the plug that goes to the dash harness.

Dan

 

those look like they plug up into the white plug that powers your injectors

 

everything works on the dash so i dont think its that. there is nothing there for the blue plug to plug into.

so the cut harness might run the injectors. so it would plug into the engine harness

 

Right hand drive car?

 

yes

 

Not positive, but if its all comes out of the same loom at the blue connector and the PCME connectors than it could be the PCMT wires. its the transmission control unit for AT 7s. the connector is in all cars, but doesnt connect to anything in MT cars.

 

it connects to the firewall harness, its located behind the heater/AC blower and right above the engine harness grommet.

i was wiring my fuel pumps in that area so i was able to snap a picture for you, I'm also right hand drive.

 

cool thanks, ill see if there is a plug there. do you know what it controls? also do you know what the cut harness is.

 

i connected the blue plug so that one is done. what a pain it was without taking the dash out. so can anyone id the cut plug and where it would connect.

 

What does the writing on the tape say? that may help shed some light on it.

EDIT: I'm not positive about RHD cars, but on USDM cars there are 4 yellow plugs going to the PCME. I didnt see the other 2 in your pic which is why i was asking.

 

it just has the color of the wires written on them, the motor harness is not in the car yet.
