I think the Ignition switch is like this:
brn/w - Voltage regulator 4
ppl - direct to Solenoid S
p - goes all over the place including Solenoid R (may turn into a white or ppl wire at sol)
r - fuse panel power
I'm guessing you're not much into the wiring diagrams but as suggested you may want to find one and take a look. Finding a factory harness might also be a good idea. Good luck.
