I have 1984 533i with a bad ignition switch. Wired in a toggle switch from auto zone. Connected red power to one terminal and green and violet to the other terminal. Power comes when i flip the switch, then i touch the black wire to the power red terminal. Car cranks but doesnt start. Cannot figure out where to connect the two thinner wires, one is brown ground the other is brown/yellow. Keep in mind the ignition switch is broken and I cut all the wires from the switch

Thanks in advance
