Controls in place, we could at least push our LS-powered 2003 Nissan 350Z around the garage. But driving was the goal, so we needed to work on reinstalling the wiring next. The car’s body wiring harness, all 13.4 pounds of it, was still bundled up in a plastic bin in the corner of the garage, and the car wouldn’t run without it.

Here we faced a dilemma: Under the hood we had a plug-and-play engine-swap harness from LOJ Conversions, but it relied on its connection to 350Z’s body harness to run. In theory, we could cut away 90% of the wires (and weight) from the OEM body harness, leaving only what was necessary to run the LOJ harness connected to the engine, along with the ABS and lights. Why cut out so many wires? It saves weight, space and complexity, and means searching through 10 wires instead of 100 when we have a problem at the track.
