Swapped engines in a 2014 Mazda 3. 2.0L skyactive. Standard Trans. New engine came out of an automatic, had to swap wiring harness off original engine onto the new engine. Installed engine back into car. No spark, turns over and everything but no spark. There’s also an extra wiring clip at back of engine that I have no idea where it goes. Can’t find a wiring diagram for it anywhere on the Internet.
