Timer PCB replacement for Diplomat ADP8132?

I sent away my timer unit for repair and got a different one in return so I now don't know which way round to connect the wires to the 2 spade terminals as I had marked up the old pcb. There are 2 white wires on one terminal and a brown one on the other. They are fitted through a hole in the white plastic pcb cover. I need to know which way they go with the LEDs at the top. There is nothing printed on the pcb to indicate polarity and they connect to a relay.
