i just bought a 1990 fc convertible with a jdm turbo 2 swap. from what i can tell the previous owner tried to chop up the usdm harness to adapt it to the jdm n374 ecu and Im kind of lost with the wiring

 

I'm not one that's usually pretty good with wiring, but if you need help with wiring, you need to be a bit more specific with what you're asking. I understand you showed the connector and the wiring, but for me there's no context here and its hard to even know where to go or what you are looking for. I'm not trying to be that guy, but from past experience, you need to give more information to get a better response. Good luck. If I can help I'll be glad to.

 

This is gonna be a challenge to straighten out as it has elements of N350 (S5 NA) and N374 (JDM S5 Turbo). I have both diagrams if you're stuck.

 

That would be super useful it's a s5 na chassis with a s5 jdm swap and the previous owner moved and left it sitting so I got it for cheap and want to get her finished.

 

What kind of more specific information are you looking for? I just picked up the car so I don't know too much but I know it's a s5 vert with the jdm s5 turbo swaped in I believe I need to get my hands on a n370 ecu and try and patch together the harness but I'm not 100% sure

 

also with it having elements from both would i be able to finish the previous owners work and use the jdm n374 or would i still need to pick up the n370 ecu
