if you have a rb26, weither it be a r32,33 or 34 if you get a harness for a rb26 it should work. i dont think there are that great of if any differences between the generations. unlike the rb25 with the series 1 and 2 and the er34 neo engine there are significant differences. but do some research, if you dont find a solid answer here check the skylines downunder forums.
good luck
