Help with brake lights and wipers '72 Duster

Brake light switch is mounted to the swing pedal support, not to the brake pedal. The two holes to mount it are elongated to allow for adjustment and may be partially obscured by the steering column. The wire colors are pink and white. All cars have a switch- no exceptions.
Yes, I know all cars have em, but this car has been modified and built w/misc parts cars, thinking the assembly may not be the orig, but it may be and I was not looking high enough! I hope so, will find out to morrow.
