Back underneath the car, it was time to wire up the trans, which was pleasantly simple. The Hurst kit includes a speedometer cable that connects to the factory gauge with plug-and-play simplicity. The same goes for the reverse lights, but as with most cars that have seen 40-plus years on the road, the factory connectors on Project Olds were severely thrashed, so Jarvis hardwired them in instead. To prevent bumping the starter with the trans in gear, we hooked up a neutral safety switch as well. The Hurst setup includes fittings that screw into the starter terminals, which are then spliced into the NSS.
