Here is my last issue. If you look at the wires going into the Toro module wire connectors, they are not labeled in proper sequence. The first module on the left should be for zones 1 & 2 but the wires are labeled #4 & #6. According to the Toro set up, all my wires for zones 1 thru 8 are wrong (except for #8) so my guess is that I should go with the order that they are installed on the modules (1, 2, 3, 4, etc) & assume the hand written number on the red wire itself is wrong or irrelevant. It looks like the only wire that is numbered correctly & in the correct module location is #8.
