The best way I can help you determine which wire to install the brake switch wire of your brake controller to would be to use a circuit tester like our part # PTW2993 and test all of the wires you have found till you find one that only sees 12 volts when the brakes are applied. This would be the correct wire to use.

When we installed a brake controller on a similar Ranger as yours the correct wire to use was green. See the attached video around the 4:45 mark.

I attached an FAQ on brake controller installs for you to check out as well.
