Hi,
First time posting. Recently got an ek2 with a d13b auto and will be changing out for b18c4 shortly. Have got all the mechanical bits I need I think but need help with wiring. I was going to put engine loom and ecu from the b18c4 into the ek as my ECU is a complete mystery, not obd1/2/2a/2b, or anything I can find so can't get a harness for it. Will I have an issue with the dash loom of my ek plugging into the mb6 ECU? should I get that dash loom too with the rest of the wiring. Pictures of my ECU attached

 

Looks like a OBD2B ECU

What year EK?

 

Its a 98 ek2
Conversion is coming from a mb6 1.8 bros. Loom ECU and all. The two plugs in my ECU look like plugs "A" and "D" from obd1 though?

 

This is NOT a US model vehicle. The engine harness type that you have pictured above does not match any USDM application, so identifying what "Type" of ECU plugs you have isn't important because you will have to modify ANY engine harness that you use. You will need to acquire the FSM for YOUR chassis and the FSM for the chassis in which the engine swap you intend to use comes from. Then, you can compare wiring data and build a custom engine harness that works with your instrumentation and runs the engine.

 

Cheers,I'll have both looms and get a pinout for both and do what I can. Thanks for your help!
