Quoted from BubbaK:I am also missing the labels on the first 2 relays on the left side. The letters fell off the relay so not sure which ones they are.
Here is the reference photo for Super Spin, which might have the same relays:

Or you could just use your schematic to identify the relays by comparing coil numbers, wire colors, number of switches, etc..
