Thats the question folks. I have been reading lots of posts, just looking for opinions here. If I properly solder the wires on the jdm harness to make them longer, would it be easier to do so then to take apart my S5n/a top end/jdm s5 top end to swap out the harnesses? I know there are a few other things I would have to do to the n/a harness, but everything is already hooked up the the JDM engine. Im pretty lazy so the JDM harness looks easier to me

 

JDM harness dont have the same connectors and pin config as US spec and eu spec harness.. I had some issues with that!

 

I have the JDM ecu. Were you having problems with your body harness or what?

 

I dont remember exactly but if you got the jdm engine harness and jdm ecu it should be possible! I just remember that i couldnt really use the wiring diagram from the internet because of different colors on wires and pin config..
In the end i went with a microtech lt8..

 

I hope so. Thanks for the input Sindregutt....anyone else?

 

it wasnt much :S Many years since i was doing that JDM swap.. Strange that nobody else knows thought!
Good luck!

 

even with the jdm ecu you will still have problems. some of the us body harness cant plug in.. things like cas and alternator. just do it right and get a us spec t2 harness and compy.

 

Would you like to donate to the cause, there Steven? **** looking like if I can find one its like $150. But I found some threads on the N/A wire harness nad that you only have to swap a couple wires. Hit me up on Forza sometime and we can discuss it further. VANDAMN93
