So I recently just bought Vq35de AT tranny with harness all cut so I had my old motor still started taking parts off too complete new everything bolted in just fine but when it came to connecting harness to tranny I realized it only had one plug so my old harness came with 3 plugs I was so confused the motor is from 2003 too 2006 it said perfect fit to my sedan it fits but the tranny clip would work cuz it’s 3 plug can I just grab the same harness that came cut and hook up motor to new ecu that came the new motor ?
