Wiring Schematic diagram for Bosch Exxcel Maxx Dishwasher please?

I have a Bosch Exxcel Maxx (slim) Dishwasher. I bought a motor and replaced the old one because it had seized up. I made sure the new motor matched my dishwasher when I ordered it. I noted the wire connections before I disconnected them. However, I am not able to reconnect all the connectors I disconnected. After I removed the old motor, I discovered the following: a. the old motor (previously installed by a freelance engineer) and the new one are not exactly the same b. the black wire which was connected to terminal 4 on the old one would not fit onto the same terminal on the new motor c. a violet wire with a spade connector had been taped to the wire bundle, i.e. it wasn't connected to anything; I remembered the engineer had some minor issue when he installed the old one, I think he might have done this. d. also there was no wire connected to terminal 1 on the old motor. Could someone tell me/show me which wires should go where please? The terminals are labeled 3 2 4 1. There are also 2 wires ( 1 red and 1 black) with female spade connectors on the ends - these connect to the capacitor. Many thanks.
