great! its basically two parts you have the cable that runs under the car to the front then you have the upper part that runs to the battery, and it joins together. the sheet metal of the truck seperates the two peices, basically its how bmw wired up the batery cable through the trunk.
if you have a picture i can tell you if its the right thing.

not to worried about coupe or vert as its going to be fabricated anyway. as im moving the battery from the trunk to the area of the amp near the back wall, its going to be a smaller dry cell battery ofcourse.
thanks a billion.
