I have been reading a ton on this site and am ready to post wiring directions on the combo switch for those of you using an EZ Wiring harness. There may be some differences between what model combo switch you have; the one I am working with is off of a 260z and has a 9 pin wiper connector. Some of you may disagree with my wire labeling; well you are wrong; I got it from a guy who restores the combo switches and has done so for over 2 decades. I am going to trust his info and my success with wiring. You will notice a few changes in my chart than in previous posts by other members. Again, I know mine works and has not been altered in any way from the original Datsun wire colors and functions. Let me know if you have any questions. I am running a full LED lighting system around the car.
