Started wiring up the p-24 based on snowy rivers schematic. Had to make a custom bracket that will hold the 646 and 644 timing units to the original side plate. Pick up some wire today and will be picking the main on/off switch and lights as needed to indicate pw on,Etc. Snowy Rivers if you happen to see this post would you be willing to enlighten me on which latching relay you chose to use as there several choices. To be continued. :coolsmile:
