My daughter's first car. Previous owner had an amp or subwoofer mounted in the trunk and has the + battery cable butchered. Odd looking metal thing that is bent up has two large cables leading away to engine compartment. one cable goes to the starter towards front of the engine and other goes towards the firewall. This actually just sits on top of the battery post and can't be tightened. Never seen anything like it. Bendable and flimsy like tin. Then there is an actual clamp sitting on top of this metal on the battery post but it doesn't get very tight. this has two cables coming from it as well. One going to the trunk and the other to the fuse box. Anyway, it has been giving her problems starting since that [censored] tin like clamp on the bottom doesn't even fit tight and there is no way to tighten it. She knows to pop the hood and jiggle the connections to get it to start but what a pita. To get to the point can someone confirm that I need Motorcraft part # WC-96029 for this car? It is a 3.0 liter AWD Ford Fusion. Unless there is another way to repair it.
