We have a crossfire injection motor and are looking for the relay switch or at least an actual name for the part so I can find it. We unhooked the solenoit and applied power to the flappers and it works, so I am assuming from research that this means it it the relay? Any information would be much appreciated.

 

Yes, there is a relay mounted on the fire wall next to the Fuel Pump Relay that takes a siganl from the ECM and under WOT (wide open throttle) will energize the solenoid relay and open the flaps. Different references have the mounting arrangement different as to whcih relay is on the left and which is on the right at the mounting locations. In my 82 it is mounted on the right. Looking at the fire wall from the front of the car, you will see two realys and the MAP sensor on the fire wall, just in front of the dirver's seat. MAP will be on left side, next will be Fuel Pum Realy, next will be hood solenoid relay, then left fender. Let me know if you need some more info.
