Sorry, can't remember right off. I used a multimeter with a continuity checker to find mine. Before I had a multimeter, I used to use a rig made from a flashlight bulb, some wire, and a battery (D cell). Same thing. Since there are only 4 wires, hook it to the transmission and find out which 2 wires have continuity (or light the bulb) when the tranny is in N or Park. then the other 2 will have continuity when the tranny is in R.
If the tranny isn't in yet, you can still move the linkage and find out. Reverse lights up in one position while the neutral switch light up in 2 positions. Not hard to do with the proper tool (s).
