Hello I need some help. I have an Canon 400D, and 2 inon z-240, but they don´t work in ttl without a converter. Last year I bought a Heinrichs-Weikamp e-ttl mk III converter, but never used it, for one simple reason, wich are the pins I have to soldering the 3,6V battery, could you help me please? Regards Diogo
