I got mine at Shuck's Auto supplies. I'm pretty sure their stores are nation wide. They have all kinds of quick female disconnects, but I'd suggest the red ones, forgot exactly how big they are. I bought a pair of blue ones as well, but they were a tad bit big, they worked, but I had to crimp em REALLY tight, it was kind of a good thing though cause I had blue for grounds, and red for positives (whatever the one that is always changing), so it was kind of color coded.
