I need to know what wires go where on the ignition switch. I got one white wire whitch I think is for the coil,cause my plug wires spark when i give that wire power.

Mike, The white one is power to the switchbox, from the ign switch. Brown is tach sender. Grey is choke solenoid, black is ground. The solenoid wire runs thru the neutral start switch. Red is likely power.
