The pics above are from a Williams design flipper. You want pics of a Bally linear flipper.
Unfortunately, my Strange Science is folded up in storage so I can't take pics for you, but if you go by the schematic above you should have:
Outer lug of coil with BANDED end of diode: Solid brown wire from harness and one wire going to first (normally closed) EOS switch.
Center lug: Second wire going to first (normally closed) EOS switch.
Outer lug of coil with NON-BANDED end of diode: Grey/white wire from harness and one wire going to 2nd (normally open) EOS switch. The other wire of the 2nd (normally open) EOS switch should be grey/black which goes back into the harness and connects to the upper flipper.
You can compare this to the left flipper. You should have the same connections on the outer lug with banded end of diode as well as the center lug. The wire on the outer lug with non-banded end of diode should be solid grey and will be the only wire on that lug since there isn't a 2nd EOS switch on the left flipper.
