Here’s a picture of the BIRD in my 2016 Axis - right next to the Trombetta. If you have a BIRD rather than a BCC and the Trombetta does not fix your problem, check the voltage on the orange wire coming out if the Trombetta. It should read the same as your chassis battery. If it does not, it may be hooked up incorrectly (as one of mine was from the factory). That wire senses the charge on the chassis battery to open and close the Trombetta
