You'll have to take a Dremel to the cover that goes on the end, at the main power connection on the PDC. I made a slot. Situated about 1/8" back from the front corners of the cover, both sides. The slot is about 1/2-5/8" wide, and just deep or long enough to fit over the cables, so that they don't rub. I'd say that the slot is about 1.5" deep ? Yours may be different, especially if you are using 2ga wire. So make sure you don't remove too much !
