Just wanted to know if I could use a us spec harness on a jdm 2jz tt or do I have to use the jspec harness. I guess another question that can go with this one would be since I am planing on going with the AEM system can the jspec harness pulg in and work with it

Thanks in advance

 

can anyone answer this question

 

no, your gonna need a us spec tt harness, and the jdm harness, and cut and splice the jdm harness onto the supra harness. Just the ones that are on the engine, and then you can run a stand-alone, or stock tt supra ecu. Just depends if your willing to do that. Not many shops do that kina things. A usdm harness used will run about 500-700 dollars depends on the condition. Well good luck I would go jdm thats what im doing. A little longer, and harder, but for the price its worth it...

 

thanks for the reply. So your telling me that the jdm harness cant be used with the AEM system
