FWIW, I used the Rostra switch with circuit reversing relays and my cruise did not work. So, I started tracing circuits to see where I went wrong. In the end, it turned out to be a mis adjusted brake light switch that caused the normally closed portion (that the cruise power circuit connects to) to be normally open. Readjust the switch and bingo. Love it!
