is it possible that the jdm ecu when i tried to start it and when it burned up the ground wire that ran to the passenger side fender from intake manifold that it also burned up another ground wire? maybe inside the harness
i replaced the ground wire from the intake manifold to the fender with alot bigger ground wire This post has been edited by stormmage88: Apr 19, 2012 - 9:54 PM |
