Hi Dom do you all ready have the wire soldered to the inside of the Eheim feeder for power and the other set for control of the feed drum?
if you do on the connection board there is a usb port named feeder it has 3v gnd data and extra pin so only 3 out of the 4 pins are used I just plugged in the usb cable then used a volt meter to find +v and gnd and then just tried the other 2 wires till I got the data wire white I think
