Sounds like you have the frame mounted battery. I am attaching instructions to get remove it.

is there any way to access the positive flow from the alternator without removing the battery box, i literally am just trying to attach a 2awg cable to the positive flow circuit through which i'll put a solenoid isolator. I could always remove the batery box, but i would prefer not too.
Customer: replied 9 months ago.
this is how one chap accessed it although i'm not sure how, and he doesn't remember. there's only rubber there as far as i can tell
Expert:  Jeremy replied 9 months ago.

On that, pop the rubber cap, remove the 2 volts on each side of the hold down, use a 13 mm wrench and remove the battery cable hold down. Then install the isolator and go backwards from there. Other option is to install that on the starter cable at the starter. That is where all the power flows from on these vans. It all goes through the starter then to a voltage mount on the fuse box.

Depending on the isolator's job, you can mount it on the alternator cable if it is to keep from having spikes.
