I just bought an fd and it looks like they replaced the engine at some point and it never ran right after that, the engine sounds healthy but at around 3800 rpm under load it has a miss like fuel cut. I was wondering if my wiring harness is the correct one. it's got a black box where all the solenoids are built in to one. and it doesn't have most of the emission ports. I'll post pics later today

 

That is a JDM black box (96+). If it is the correct harness for that engine, it is not the right harness for the car (assuming a USDM car).


What year car do you have?
What ECU?
Is the Car RHD?

Just checking the car in your sig is the one you are talking about.

 

i just pull harness out and it looks like they spliced the connectors
to the original harness to use the black box. is that some kind of mod?
by the way the car is a us model 93
