We are doing a swap and we are missing the part of the engine harness that runs between the blue and grey connectors and the ecu in the above picture. Is that harness section ej18 specific?
Engine will be a non turbo DOHC ej25 using the ej18 ecu, throttlebody and wiring. All put into a 95 impreza sedan.
Transmission is a jdm 4.11 box.
The 4eat 93 impreza I have has different connectors on it. top one is round on 93.
Does anyone know when they switched from the round connectors to the square ones show here? Is the wiring different or are just the plugs different?
When did they switch to obdii?
If the 1.8 wiring and ecu don't work right we will try a 2.5 ecu and harness merge.
