His eyes drifted to the and NE+ pins. These were the crankshaft and camshaft position signals. If the ECU didn't know exactly where the pistons were, it wouldn't dare spray a drop of fuel. It was a safety protocol, a digital handshake that had to be perfect.
Elias didn't just twist the wires together. He stripped them back, soldered the connection with the precision of a jeweler, and sealed it with marine-grade heat shrink.

He stepped back into the cabin, plugged the three massive headers into the ECU, and turned the key. The dash lights flickered to life—the "Glow" indicator faded, and the "Check Engine" light, which had been a steady, mocking amber, finally blinked out. His eyes drifted to the and NE+ pins
