This is my BBOD (big box of doom). I have a MAP Sensor and a Map Sensor Control Solenoid (atmospheric pressure changeover solenoid). Earlier and Later models have neither in the BBOD: View From the Bottom: Loom Plugs: Exhaust Gas Control Valve Duty Solenoid removed, Map Sensor removed, Map Sensor Control Solenoid removed: I\'ve wired 2 LED lights, one to the ECV Duty Solenoid to see exactly when it is bleeding (duty cycle). The other LED is wired into the Map Sensor Control Solenoid
