Power and Ground Requirements
WARNING: This page is about a different car, the 2014 Lincoln MKX and 2014 Ford Edge. However, it is still accessible from the selected car via links, so may be relevant.
The Body Control Module (BCM) fuse 9 (10A) supplies battery logic power required for the software and internal switching operations. Power is supplied to the motor by Battery Junction Box (BJB) fuse 7 (30A).
Ground for the Liftgate/Trunk Module (LTM) is a separate single connection. Some of the continuous inputs which are at a ground state when on, are also used for logic switching.
