I am replacing my Rainbird RC-1260 with the gen-1. Got it all installed and wifi hooked up but the sprinklers will not turn on. The plug has 15 pins. 12 are for the zones then there are for zones-brown, red, orange, yellow, green, blue, purple, gray, white, blk/white, Brn/White, and Pink/white or might be red/white. The last three were not used as I only have 9 zones. Along the bottom row are red/white, and brown/white. These were hooked to the transformer leads and are marked Line Input. The other bottom plug pin is pink/white what was not hooked to anything. I have corresponding wires in the cable sheath along with a black wire which I assumed was common. I put the black wire in the common and zones do not operate. I put the black wire in the master location and zones to not operate. Can someone tell where I am going wrong?
