k
its on the side under the plastic cover that lifts straight up
there are two relays and one has blue paint on the screw and one has green paint on the screw for color coding
i never could figure out which was which and never bothered to fully understand how they work but they are the same part # for both of them and how they work is they reverse the polarity for up or down and they cost around $80 each
the common ground bar connected to both allows it to work like a 3 way light switch or something
