I have a 90 EF hatch that had a d15b7 in it with some expletiveed up wiring. I just got a SOHC zc with a SI harness on it i need to get it running wiring wise

 

i see that all of the threads say to convert the dx harness using the si harness but i dont have the dx harness i need to make the si harness work can anyone help me

 

i have a 90 EF hatch and i know and have read all the forums and stuff saying that you cannot use the si harness on a dx car but here is my problem i got the car with no engine harness but have a full car crx si harness what is the best thing i can do could i cut and match the under the dash to the crx si ecu plugs and engine harness or would it be easier to replace the whole under dash harness i dont have anymore money at the moment to put into this car but i do have time

 

someone please help

 

I can hardly comprehend your post, but if you do have the full car crx si harness, it seems to me that you would not have to cut anything? I'm confused...

 

ok the si harness will work just connect it to the motor as is and then plug in the 2 plugs that are the same now for the other plug u have to run wires to the ecu for that. I dont have the wiring diagram but can look around.
