im still mystified on how a regulator works.(just pick any till it reads appropriately)
step 2. power up the regulator: wire stator to first spot on regulator
once regulator is powered up.
step 4. now you have 3 empty choices on regulator..., pick one and split to brake switches.
or narrow it down with a running motor and a voltage tester out in fresh air.
good luck just do it.
