Power and Ground Requirements
WARNING: This page is about a different car, the 2007 Lincoln MKX and 2007 Ford Edge. However, it is still accessible from the selected car via links, so may be relevant.
The smart junction box (SJB) fuse 14 (10A) supplies battery logic power required for the software, clutch and internal switching operations. Power is supplied to the motor by bussed electric center (BEC) fuse 27 (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.
