Yea i used the stock LX wiring harness. I still dont see how the wiring harness could cause your over heating. If its a bad ECU then you could have problems. I never hooked my vtec up and my car ran strong and never over heated. But if you can put the old ECU in and it works fine then im putting my money on the ECU. Also when you install the ECU are you letting the car sit at a steady idle for about 10-15 minutes. You have to make sure you let everything recalibrate in a way/
