ok so if im reading this right pins 14 and 15 need to be used for ign. sense then? im just wanting to make sure so i dont turn my radio into a dang brick!

Only connect it up to the pin 15, ignition input. The pin 14, SW B+ is actually an output pin from the radio
to supply +12 volts to options with limited current, when the radio is turned on.
