3B is the 12V starter input signal for the ECU, it lets the ecu know you are trying to start the engine. im not exactly sure how it works, but the ecu may use this to use a priming fuel map instead of the base map. could be the reason your not starting
im not familiar with FB's, but you could wire it into the same wire that goes to the starter solenoid
