I made my own cables and secured the big mess of wires outside of the battery tray. Neatly of course! Batteries were GC2"s 6vdc. 10.25 long x 7 1/8 wide x 10 7/8 high. Which reminds me. I had to lower the whole tray as well by 1.5 inches to accommodate the taller batteries and to account for how they must be installed. Which is slid through hole in the step lengthwise then rotated 90 degrees. Had to slide the first one all the way forward 2nd and 3rd all the way aft. install the 4th one and then slide them all forward.
