The Wiring Specialties wiring service is for those looking to send in their existing harness for modification. If you are looking for a new harness to purchase off the shelf, please see our pre-made section.
This wiring service and conversion only applies
to the R33 RB25DET engine installed into a S14 240sx chassis. If you do not see your engine or
vehicle in the list, please check other available items.

NOTE: The Speed signal and the RPM signal of the Skyline sensors are different from what the 240sx gauge cluster expects. A frequency modulator might have to be used to get the speed and RPM to display correctly in a 240sx. We have had good luck with the Dakota Digital SGI-5 unit.
