It's not an EC3, it's an HXT connector, basically just a bullet type plug with a plastic housing. I would switch everything to Deans. There are other connectors out there, like EC3, but Deans is easily the most common aftermarket connector, and can be found in every hobby shop.
can say the same about traxxas, and traxxas prolly can be found in pepboys
thx for correcting about the hxt been a while since I looked at EC3's
