Wiring and exhaust
This was the first LS harness I had ever done. I striped the entire loom down to each circuit then put the PCM where I wanted it and re-connected all the wires, extending or shortening as needed.
Next step was exhaust. This was going to be my daily with a newborn so I wanted something QUIET. It ended up with cats, 2 into 1 Spintech followed up by a straight-through Magnaflow. It sounded like a factory car with zero drone at highway speeds but excellent scream when on it.
So many wires
PCM in it's new home (oh an AC lines)
