The Wiring Specialties 300ZX Alternator to Trans (manual) harness is now available as a plug and play alternative to the high priced OEM replacement.
Due to decades of under-hood heat exposure and often leaks in the engine bay, problems are commonly found in this neglected harness; starting issues, erratic or inoperative gauges, reverse lights not working, and charging systems problems have all been found here in our shop on customers cars at one time or another. Until now the only option was either patch repairs on harnesses that are already in bad shape, or a new replacement harness that list for over $348.00.
Don't let your stubborn, old harness cause you problems any longer. Freshen up that engine and eliminate future worries or electrical problems. Converting your Z from Auto to 5-speed? We now offer a harness to make Automatic to 5-speed conversions easier than ever; while keeping actual factory style connectors in the harness so it can easily be disconnected in the future if needed (without having to cut hardwired connections). With this conversion harness you will only have to make 2 cuts and 2 splices to get your reverse lights working, the rest of this harness will be plug and play.
