I’ve recently started delving into the Nissan consult port for 1991 through 2001 model year, specifically for (R)PS-13/S14/S15/R32/R33/R34 and their various spin-offs. If you ask to be more precise, I would answer the USDM S13 and S14. In reality, there was no USDM VIN specification with (R)PS-13 nor S14 in the alphanumeric sequence. The 240SX is related to their Japan, European and Australian cousins in chassis only. The 240SX engines, ECU and wiring is different. One of prjktMAYHEM’s first tasks is to confirm/validate that some Japanese-made electronics can be plug-and-play in the 240SX through the consult port. Stay tuned for update.
