Hi Jack,

I just happened to have a unit like this in a box in the garage. Once you get the round cover off, hold the unit so the white valve is at 4-o'clock and the black valve is at 8-o'clock. Yellow-brown wire goes to the white valve connector closest to 3-o'clock. Yellow-red wire goes to black valve connector at 9-o'clock. Red-white wires go to the valve connectors closest to 6-o'clock.

I put a couple of wire-ties around the cable just inside where it comes through the side of the unit--that way any stress (pull) is taken up by these wire-ties and not the connectors.

Hope this works for you. If not, e-mail me and I'll try to take a picture and e-mail it back.

Regards,

Steve A-
