So the two first picture are plugs that connects to the ecu..I was woundering what kind of harness this is GSR ITR...etc.....

31P

25P


Second this wire was cut and i have no clue what its for. i've search and look in my Haynes book and nothing.
Yellow with Red stripe

 

someone has to know..

 

Hard to say, there is more then one yellow/red lead in the car.

Engine oil pressure switch lead is yellow/red running to gauge assembly and ICU.

There is a yellow/red running from heater control unit, [vent switch] to mode control motor.

The radio harness has a yellow/red, [radio acc. power].

Onr of the leads from the manifold absolute pressure sensor is yellow/red but changes to yellow/white before connecting to ECU/ECM (VCC1), 98 Integra only.

All but the above seem to be common to 94-98 Integra. 94

 

THATS IT!! its for the oil pressure....wow i cant believe i didnt catch that.

One more question on top of what i've already ask....if im not using the o2, oil pressure, and knock can i just take the connectors off and tape off the pins and save it in the engine harness sleeve? Im doing a mild wire tuck and i dont want extra connectors hanging around, but want to save for later if i needed it.

 

Haynes book does not have a oil pressure in their wire diagram!

 

What Haynes are you looking at?

My Haynes #42025 shows EOPS on page 12-45. [94 Integra] and page 12-47, [95 - 98 Integra]. 94

 

I also have the 42025 i see the EOPS on page 12-47 but not on 12-45

 

That is an OBD2b harness for sure. At first I had to check to make sure it wasn't an OBD2a with automatic connectors, but the wires are not in the right location for the auto functions on the B plug for it to be OBD2a. Assuming nothing has been modified, that looks to be a 99-00 Si harness or TypeR. I don't believe it is a GSR harness because the IAB control solenoid valve wire that is at B16 (25P connector) is not there. I don't think it is a LS harness because it looks like (hard to tell from these angles) that the vtec wires are there. Given the location on the Yel/Red it is probably to the oil pressure switch dummy light.

But I am certain that is an OBD2b harness.

 

you are the man.. if you ever get into a fight i got your back!
