Thanks for the response. Not listing the derailleurs was an over-sight on my part. It's the variety of installations with different shifter buttons and/or a wireless piece (?) that is confusing me. I've done a Campagnolo EPS Record installation and it was pretty straight forward. A wire from each shfter to an interface unit, a wire from that unit to the battery, and then two wires from that, one to the FD and one to the RD. Easy-peasy.
